LORa RF Module Application: PLC Touch Screen with Flow Meter

LoRa RF Module use in this project is LoRa611Pro

Description: 

LoRa611Pro is a LoRa RF module, based on SX1276/1278 chips from Semtech. This module adopts LoRa technology to achieve high effective sensitivity and superior anti-interference. The communication distance and receiver sensitivity are far exceeds the FSK, GFSK modulation. For better security, the module uses AES128 encryption.

The LoRa611Pro module is designed for 100mw output power and is available in TTL/RS232/RS485 levels. It is widely used in wireless remote transmission control.

LoRa611Pro strictly uses lead-free process for production and testing, and meets RoHS and Reach standards.

Note: The LoRa Pro series can be configured to be compatible with our previous uart LoRa modules.

LoRa RF Module: PLC Touch Screen with Flow meter

1. Application:

The flow meter read teh flow data, and connected the LoRa611Pro via serial port. LoRa611Pro transmit the flow data to the receiver LoRa611Pro that connected to the PLC touch screen via RS485. And display the flow data on PLC.
