Overview

R718PE is a wireless communication device that uses ultrasound to detect the distance between the device and the detected object. The medium the device detects is the air, so the detected object can be any liquid or solid that has a flat and horizontal surface, water level for example. The main body and the sensor of R718PE communicates via the UART serial port, and the detected data can be transmitted via LoRa communication.

Introduction

R718PE is a wireless communication device that uses ultrasonic to measure distance. The ultrasonic propagation medium of R718PE ultrasonic sensor is air, so the measured object can be any liquid or solid with a certain flat. The device can be used for liquid level detection, material level detection, etc. The host body and the ultrasonic sensor communicate through the UART serial port and transmit the detected data to other devices through the wireless network for display. It adopts a wireless communication method that conforms to the LoRaTM protocol standard.
