LoRaWAN Ultrasonic Distance Sensor Solution: DYP-A02 with KC21 and ThinkLink

1. Solution Overview

In IoT deployments, low power consumption, long-range communication, and stable data acquisition are critical.

This solution integrates:

DYP-A02 ultrasonic sensor

KC21 with EdgeBus

LoRaWAN gateway

ThinkLink IoT platform

to build a complete wireless distance monitoring system.

1. DYP-A02 Sensor Features Feature Description Small blind zone Only 3 cm Multiple interfaces Modbus / UART / PWM / Analog წყალproof design Suitable for harsh environments Operating temperature -15℃ to +60℃ Ultra-low power Standby current < 5 µA
2. System Architecture DYP-A02 (RS-485 / Modbus) ↓ KC21 (EdgeBus) ↓ LoRaWAN Gateway (GDO51 / GDI51) ↓ ThinkLink Platform
3. Data Acquisition

Only two registers are required:

Register Data Unit
0x0100 Distance mm
0x0102 Temperature 0.1℃

1. Remote Configuration (RPC)

Parameters adjustable via ThinkLink:

period_read – sampling interval

period_up – upload interval

cov_distance – change threshold
