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.
2. DYP-A02 Sensor Features
