2. Appearance
3. Introduction
The R718PA22 is a wireless communication device that measures the liquid level with an ultrasonic liquid level sensor. Ultrasonic liquid level sensor
installed at the bottom of the container, it may measure water, gasoline, diesel and small, medium, large capacity storage tanks (metal, plastic, glass
material). R718PA22 main unit and the ultrasonic liquid level sensor communicate via RS485 interface, and the detected data is sent to the other
equipment shown which employs compliance LoraWAN
TM
wireless communication protocol standards.
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.
