1. Introduction
R727 is a ClassA type device based on LoRaWAN open protocol, compatible with LoRaWAN
protocol.
R727 carries RA07 which can connect a variety of sensor, plus multi-layer mask, bracket, DC power
supply for outdoor use. A variety of sensor combinations are required for specific requirements. A
variety of sensor combinations are required for specific requirements. As PM2.5, temperature and
humidity, CO, NO, liquid level, and soil detectors, the data collected by sensor will be reported to
the corresponding gateways.
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.
