ESP8266 IoT Temperature and Humidity Monitoring with KiwisIoT

Introduction

Have you ever wanted to monitor the temperature and humidity of a room remotely?

In this project, I developed an IoT-based temperature and humidity monitoring system using an ESP8266 NodeMCU and a DHT11 sensor.

The DHT11 sensor collects environmental data, and the ESP8266 sends the readings through Wi-Fi to the KiwisIoT Dashboard. Users can view temperature and humidity values remotely through the dashboard.

Project Overview

This project has three main components:

DHT11 Sensor: Measures temperature and humidity.
ESP8266 NodeMCU: Reads sensor data and sends it through Wi-Fi.
KiwisIoT Dashboard: Displays the received sensor readings.

How Does It Work?

The DHT11 sensor measures the surrounding temperature and humidity.
The ESP8266 reads the sensor values.
The ESP8266 connects to Wi-Fi.
Sensor readings are sent to the KiwisIoT platform.
The KiwisIoT Dashboard displays the temperature and humidity values.

Data Flow:

DHT11 Sensor → ESP8266 NodeMCU → Wi-Fi → KiwisIoT Platform → Dashboard

Circuit Diagram

[INSERT CIRCUIT DIAGRAM IMAGE HERE]

The DHT11 sensor receives power from the ESP8266. Its DATA pin is connected to D1, which allows the ESP8266 to read temperature and humidity measurements.

KiwisIoT Dashboard Configuration

The KiwisIoT platform is used to receive and display the sensor readings.

I configured two data channels:

Channel	Parameter	Unit
Channel 0	Temperature	°C
Channel 1	Humidity	%

Two dashboard widgets are configured:

Temperature Widget: Displays temperature readings from Channel 0.
Humidity Widget: Displays humidity readings from Channel 1.

The ESP8266 sends the sensor values to the corresponding channels.

Arduino IDE Setup

Before uploading the program:

Install Arduino IDE.
Install the ESP8266 board package.
Install the KiwisIoT Arduino library.
Install the DHT sensor library.
Install the Adafruit Unified Sensor library.
Select the ESP8266 NodeMCU board.
Select the correct COM port.

Arduino Code

The following Arduino program reads temperature and humidity from the DHT11 sensor and sends the values to the KiwisIoT Dashboard.

Replace the Wi-Fi name, password, and dashboard Topic ID with your own details before uploading.

#include <ESP8266WiFi.h>
#include <KiwisIoT.h>
#include <DHT.h>

const char* ssid = "YOUR_WIFI_NAME";
const char* pass = "YOUR_WIFI_PASSWORD";
const char* topic = "YOUR_DASHBOARD_TOPIC_ID";

#define DHT_PIN D1
#define DHT_TYPE DHT11

DHT dht(DHT_PIN, DHT_TYPE);
KiwisIoT kiwisiot(ssid, pass, topic);

void sendDHTData() {
  float temperature = dht.readTemperature();
  float humidity = dht.readHumidity();

  if (isnan(temperature) || isnan(humidity)) {
    Serial.println("Failed to read DHT11!");
    return;
  }

  Serial.println();
  Serial.println("---------- DHT11 MONITORING ----------");

  Serial.print("Temperature: ");
  Serial.print(temperature, 1);
  Serial.println(" °C");

  Serial.print("Humidity: ");
  Serial.print(humidity, 1);
  Serial.println(" %");

  String temperatureData = String(temperature, 1);
  kiwisiot.send("0", temperatureData);

  Serial.print("Sent to KiwisIoT Channel 0: ");
  Serial.println(temperatureData);

  String humidityData = String(humidity, 1);
  kiwisiot.send("1", humidityData);

  Serial.print("Sent to KiwisIoT Channel 1: ");
  Serial.println(humidityData);
}

void setup() {
  Serial.begin(115200);

  Serial.println("DHT11 MONITORING");

  dht.begin();

  Serial.println("DHT11 initialized");
  Serial.println("Connecting to KiwisIoT...");

  kiwisiot.begin();

  Serial.println("KiwisIoT initialized");
  Serial.println("Starting monitoring...");
}

void loop() {
  kiwisiot.run();

  static unsigned long lastSend = 0;

  if (millis() - lastSend >= 2000) {
    lastSend = millis();
    sendDHTData();
  }

  delay(100);
}

Understanding the Code

1. Library Inclusion

The program uses the ESP8266 Wi-Fi library, KiwisIoT library, and DHT sensor library to communicate with the hardware and platform.

Ultrasonic Sentinel KiwisIoT: ESP8266-Based Real-Time Distance Monitoring

Hello, DEV Community! 👋

I'm excited to share my IoT project, Ultrasonic Sentinel KiwisIoT, built using an ESP8266 NodeMCU, an HC-SR04 ultrasonic sensor, Arduino IDE, and the KiwisIoT platform.

This project measures the distance between the sensor and a nearby object and sends the readings to a KiwisIoT dashboard over Wi-Fi for remote monitoring.

🛠️ Components Used

ESP8266 NodeMCU
HC-SR04 ultrasonic distance sensor
Jumper wires
USB cable
Arduino IDE
KiwisIoT dashboard
Wi-Fi connection

🔌 Circuit Connection Diagram

The HC-SR04 ultrasonic sensor has four pins: VCC, GND, TRIG, and ECHO.

HC-SR04 pin	ESP8266 NodeMCU connection
VCC	Suitable 5 V supply
GND	GND
TRIG	D5 (GPIO14)
ECHO	D6 (GPIO12), through a voltage divider

The TRIG pin initiates an ultrasonic pulse. When the pulse reflects from an object, the ECHO pin provides a signal whose duration is used to calculate the distance.

Safety note: The HC-SR04 ECHO output can be 5 V. Use a resistor voltage divider to reduce it to a safe level before connecting it to an ESP8266 GPIO.

⚙️ How It Works

The ESP8266 sends a trigger pulse to the HC-SR04.
The sensor emits ultrasonic sound waves.
The waves reflect off a nearby object.
The sensor returns an ECHO pulse.
The ESP8266 calculates the distance in centimetres.
The measured value is sent to KiwisIoT over Wi-Fi.
The dashboard displays the latest distance reading.

The program is designed to update the dashboard approximately every two seconds.

☁️ KiwisIoT Dashboard

I configured a KiwisIoT dashboard with a numeric widget labelled DISTANCE. The ESP8266 sends distance readings through Channel 0, allowing the dashboard to display the latest received value.

In my captured dashboard screenshot, the displayed reading is 7.41. The unit should be set to centimetres if the program is sending centimetre measurements.

This provides a simple way to observe sensor readings without relying only on the Arduino Serial Monitor.

🧪 Live Test Result

The hardware consists of an ESP8266 NodeMCU connected to the ultrasonic sensor using jumper wires and powered through USB.

The dashboard screenshot captured during testing shows a numerical reading of 7.41. To verify measurement accuracy, compare the displayed distance with the actual distance measured using a ruler or measuring tape.

Expected observations:

A nearby object produces a distance reading.
Moving the object changes the reading.
If no valid echo is received, the program reports an invalid measurement in the Serial Monitor.
If Wi-Fi is disconnected, new remote dashboard updates may stop.

💻 Arduino Code

The following Arduino sketch reads the HC-SR04 sensor and sends valid distance measurements to KiwisIoT.

Replace the Wi-Fi credentials and dashboard topic with your own values before uploading.

#include <ESP8266WiFi.h>
#include <KiwisIoT.h>

const char* ssid = "YOUR_WIFI_NAME";
const char* pass = "YOUR_WIFI_PASSWORD";
const char* topic = "YOUR_DASHBOARD_TOPIC_ID";

#define TRIG_PIN D5
#define ECHO_PIN D6

KiwisIoT kiwisiot(ssid, pass, topic);

float measureDistance() {
  digitalWrite(TRIG_PIN, LOW);
  delayMicroseconds(2);

  digitalWrite(TRIG_PIN, HIGH);
  delayMicroseconds(10);
  digitalWrite(TRIG_PIN, LOW);

  unsigned long duration =
      pulseIn(ECHO_PIN, HIGH, 30000UL);

  if (duration == 0) {
    return -1;
  }

  return duration * 0.0343 / 2.0;
}

void setup() {
  Serial.begin(115200);

  pinMode(TRIG_PIN, OUTPUT);
  pinMode(ECHO_PIN, INPUT);

  kiwisiot.begin();

  Serial.println("Ultrasonic Sentinel KiwisIoT");
}

void loop() {
  kiwisiot.run();

  static unsigned long lastSend = 0;

  if (millis() - lastSend >= 2000) {
    lastSend = millis();

    float distance = measureDistance();

    if (distance >= 0) {
      Serial.print("Distance: ");
      Serial.print(distance, 2);
      Serial.println(" cm");

      kiwisiot.send("0", String(distance, 2));
    } else {
      Serial.println("No valid echo received");
    }
  }

  delay(50);
}

The code assumes the KiwisIoT library supports the begin(), run(), and send() methods used in this sketch. Test it with your installed library and confirm that Channel 0 is configured correctly.

Security reminder: Never publish your real Wi-Fi password in a public code snippet.

🔄 System Architecture

HC-SR04 Ultrasonic Sensor → ESP8266 NodeMCU → Wi-Fi → KiwisIoT Dashboard

The sensor measures the distance, the ESP8266 processes the reading, and the dashboard provides a remote view of the data.

IR Sentinel KiwisIoT: ESP8266-Based Real-Time Object Detection

Introduction

Hello Dev Community! 👋

I built IR Sentinel KiwisIoT, a simple IoT-based object detection project using an ESP8266 NodeMCU, an IR sensor module, and the KiwisIoT platform.

The system detects nearby objects using an infrared sensor, processes the sensor's digital output through the ESP8266, and sends the object status to a KiwisIoT dashboard over Wi-Fi.

This project helped me explore sensor interfacing, embedded programming, wireless communication, and IoT dashboard monitoring.

🛠️ Components Used

ESP8266 NodeMCU development board
IR obstacle detection sensor module
Jumper wires
USB cable for power and programming
Arduino IDE
KiwisIoT account and dashboard
Wi-Fi connection

🔌 Circuit Diagram and Connection Explanation

The IR sensor module is connected to the ESP8266 NodeMCU using three main connections:

IR sensor pin	ESP8266 connection	Purpose
VCC	Suitable power pin	Powers the sensor
GND	GND	Common ground
DO	D7 (GPIO13)	Digital detection signal
AO	Not connected	Analog output is unused

The digital output pin sends a signal to the ESP8266 whenever the sensor detects an object according to its sensitivity setting.

Important: The circuit illustration shows D6 in its simplified connection table, while the code below uses D7. For this code, connect DO to D7. If your actual hardware uses D6, change the pin definition in the code to D6. Also, verify the sensor's voltage requirements and ensure its output is safe for the ESP8266's 3.3 V GPIO.

⚙️ How It Works

The project follows these steps:

The IR sensor monitors the area in front of it.
The ESP8266 reads the sensor's digital output.
The program converts the signal into DETECTED or NOT DETECTED.
The ESP8266 sends the status to KiwisIoT through Wi-Fi.
The dashboard displays the received object detection status.

The code checks the sensor periodically and sends an update approximately every two seconds.

💻 Arduino Code

The following Arduino sketch uses the ESP8266 NodeMCU, the IR sensor's digital output, and the KiwisIoT library.

Before uploading, replace the Wi-Fi and dashboard placeholders with your own settings. Never publish your Wi-Fi password in a public post.

/*

 */

#include <ESP8266WiFi.h>
#include <KiwisIoT.h>

const char* ssid = "YOUR_WIFI_NAME";
const char* pass = "YOUR_WIFI_PASSWORD";
const char* topic = "YOUR_DASHBOARD_TOPIC_ID";

#define IR_PIN D7

KiwisIoT kiwisiot(ssid, pass, topic);

void sendObjectStatus() {
  int irState = digitalRead(IR_PIN);

  String objectStatus;

  // Many IR modules output LOW when an object is detected.
  if (irState == LOW) {
    objectStatus = "DETECTED";
  } else {
    objectStatus = "NOT DETECTED";
  }

  Serial.println("\\n--- IR SENTINEL MONITORING ---");
  Serial.print("IR Sensor Value: ");
  Serial.println(irState);

  Serial.print("Object Status: ");
  Serial.println(objectStatus);

  // Send the status to KiwisIoT Channel 0.
  kiwisiot.send("0", objectStatus);

  Serial.println("Status sent to KiwisIoT");
}

void setup() {
  Serial.begin(115200);
  pinMode(IR_PIN, INPUT);

  Serial.println("\\nIR Sentinel KiwisIoT");
  Serial.println("Initializing KiwisIoT...");

  kiwisiot.begin();
}

void loop() {
  kiwisiot.run();

  static unsigned long lastSend = 0;

  if (millis() - lastSend >= 2000) {
    lastSend = millis();
    sendObjectStatus();
  }

  delay(100);
}

☁️ KiwisIoT Dashboard Configuration

I configured a KiwisIoT dashboard to display the object detection status received from the ESP8266. The program sends the status string to Channel 0 using the KiwisIoT library.

The dashboard screenshot shows DETECTED in green. This demonstrates the status displayed by the dashboard during my test.

To reproduce the setup:

Create or open your KiwisIoT dashboard.
Configure the topic ID used by your ESP8266 program.
Add a suitable text or label widget.
Configure the widget to display the data from Channel 0.
Upload the program and verify that the displayed status changes when an object enters or leaves the sensor's detection range.

The exact dashboard configuration may depend on the KiwisIoT interface and widget settings.

🧪 Live Test Result

I connected the IR sensor module to the ESP8266 NodeMCU and powered the board through USB. The sensor's digital output was used to determine the detection status.

The KiwisIoT dashboard screenshot captured during testing displays DETECTED in green.

Expected observations:

Object detected: DETECTED
No object detected: NOT DETECTED
Wi-Fi unavailable: New remote dashboard updates may stop

The results depend on sensor sensitivity, object distance and surface, sensor output logic, and Wi-Fi connectivity.

🔄 System Architecture

IR Sensor → ESP8266 NodeMCU → Wi-Fi → KiwisIoT Dashboard

The IR sensor provides the input, the ESP8266 processes the signal, and KiwisIoT displays the received status for remote monitoring.

🌍 Possible Applications

Basic object presence monitoring
Educational IoT experiments
Proximity detection demonstrations
Entry or passage monitoring prototypes
Learning embedded systems and wireless communication

This is an educational project and is not intended to replace safety-certified detection systems.

🚀 Future Improvements

Add an LED or buzzer alert.
Send notifications when an object is detected.
Record detection events over time.
Add multiple sensors for monitoring different locations.
Build a compact enclosure for the electronics.
