1. Introduction
R311B is a long-distance Wireless Light Sensor based on the LoRaWAN open protocol (Class A).
When the illuminance exceeds the set threshold, a report will be sent immediately.
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.
This device has been certified by the LoRa Alliance and is allowed to use the following logo on the product:
