Introduction
This project uses an ESP8266 NodeMCU and an IR sensor to detect objects in real time. The detection status is sent to the KiwisIoT dashboard through Wi-Fi.
Components Required
- ESP8266 NodeMCU
- IR sensor module
- Jumper wires
- USB cable
- Computer
Software Requirements
- Arduino IDE
- ESP8266 board package
- KiwisIoT Arduino library
- KiwisIoT account
- Wi-Fi connection
How It Works
- The IR sensor detects whether an object is present.
- The ESP8266 reads the sensor's digital output.
- The system identifies the status as DETECTED or NOT DETECTED.
- The ESP8266 sends the status to KiwisIoT over Wi-Fi.
- The dashboard displays the detection status for remote monitoring.
In this project, a LOW signal indicates that an object has been detected, while a HIGH signal indicates that no object is detected.
CODE:
Applications
- Object detection
- Entry monitoring
- Smart parking concepts
- Obstacle detection
- Automation projects
- IoT monitoring systems
What I Learned
Through this project, I learned how to connect an IR sensor to an ESP8266, read digital sensor values, and send sensor data to an IoT dashboard.
Conclusion
This project demonstrates how basic sensors and Wi-Fi connectivity can be combined with an IoT platform for real-time object monitoring.
I hope this project helps beginners explore IoT and embedded systems.
