Introduction
R718F2 is a long-distance door Sensor based on the LoRaWAN open protocol (Class A).
The
device is equipped with 2-gang reed sensors, The reed switch is on (conducting) within the magnetic
range, and is off (nonconducting) when it's out of the magnetic range. The module can detect the
closing and opening signals so that the state of the door window status can be detected.
LoRa Wireless Technology:
LoRa is a wireless communication technology dedicated to long distance and low power
consumption. Compared with other communication methods, LoRa spread spectrum modulation
method greatly increases to expand the communication distance. Widely used in long-distance,
low-data wireless communications. For example, automatic meter reading, building automation
equipment, wireless security systems, industrial monitoring. Main features include small size, low
power consumption, transmission distance, 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.
