1. Introduction
Wireless 2-Gang Water Leak Detector (R311W) is a LoRaWAN device compatible with LoRaWAN protocol (ClassA). When the
R311W sensor detects a leak, it will send an alarm message to the gateway. When the sensor detects no leaks, it will send a
message that shows no leak to the gateway.
LoRa Wireless Technology:
LoRa is a wireless communication technology famous for its long-distance transmission and low power consumption. Compared
with other communication methods, LoRa spread spectrum modulation technique greatly extend the communication distance. It
can be widely used in any use case that requires long-distance and low-data wireless communications. For example, automatic
meter reading, building automation equipment, wireless security systems, industrial monitoring. It has features like small size,
low power consumption, long transmission distance, strong anti-interference ability and so on.
LoRaWAN:
LoRaWAN uses LoRa technology to define end-to-end standard specifications to ensure interoperability between devices and
gateways from different manufacturers.
