Introduction
R718PA11 is a ClassA device based on the LoRaWAN
TM
protocol of Netvox and is compatible
with LoRaWAN protocol.
R718PA11 can be connected with a liquid level sensor (RS485) and report the value of the liquid
level collected by the device to the corresponding gateway.
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 manufacturer
