Introduction

The wireless intelligent water meter consists of remote basic water meter, wireless communication modules and other components. This product can complete the data collection of point-to-point through the gateway with low power consumption, long life and two-way data transmission. It provides reliable protection for the accurate collection of real-time data; Wireless water meter uploads data to the gateway everyday automatically, then the gateway uploads data to the network platform automatically; This product is simple in structure, easy to maintain and replace, and connect with no cables. So, it is easy to install.

Communication Introduction

LoRaWAN is a set of communication protocols and system architectures designed for LoRa long-distance communication networks.

When the module is powered on, it automatically sends a join packet. If no reply from the gateway to the network, the join packet will be sent in intervals. After the module receives the network access permission message by the gateway, it pushes a packet of heartbeat data; Since then, it starts timing. Actively push a pack of heartbeat data at intervals of 6 hours.

The data upload mechanism can be timed or quantitative or both, and can also be customized on demand.
