Introduction
R718PE is a ClassA device based on LoRaWAN open protocol of Netvox. R718PE is a wireless communication device that can
detect liquid level and parking space. The device is connected to an ultrasonic sensor to detect its current liquid level or the status of
parking space, and the detected data will be transmitted to other devices through the wireless network for display. It adopts SX1276
wireless communication module and is compatible with LoRaWAN protocol.
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.
