Introduction
R718PE01 series device is netvox Class A type device based on LoRaWAN open protocol. R718PE01 is a wireless communication
device that can be used for liquid level / material level detection. This device is connected with ultrasonic sensor, which can detect its
current liquid level / material level. The detection angle of R718PE01 is about 20 °, which has a stronger transmission signal and is
more suitable for the detection of objects such as grain heaps and sand. And transmit the detected data to other devices through
wireless network for display. It adopts sx1276 wireless communication module. The device 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.
