The multi-user meter module is a new generation of intelligent remote transmission module developed by our professional technical team after years of intensive research. This module is a water meter communication module with ultra-small size and low power consumption. TTL wired communication is used to connect to the LoRa wireless collection terminal to form up to 16 meters to share a multi-user collection terminal. This method not only solves the problem of trouble in construction and wiring, but also reduces the cost of the wireless module of each meter, and has the advantages of wired meters and wireless meters.
