R718PE is a wireless communication device that uses ultrasound to detect the distance between the device and the detected object. The medium the device detects is the air, so the detected object can be any liquid or solid that has a flat and horizontal surface, water level for example.
The main body and the sensor of R718PE communicates via the UART serial port, and the detected data can be transmitted via LoRa communication.
R718PE01 is a wireless communication device that uses ultrasonic waves to measure
distance. The ultrasonic transmission medium of R718PE01 ultrasonic sensor is air, so the
measured object can be any liquid or solid with a certain plane, which can be used for liquid
level detection, material level detection, etc. 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.
The device has a built-in light sensor that can be used for ambient light intensity detection. It adopts the SX1276 wireless communication module. R718PG detects the ambient light intensity value and joins to the gateway.
The R718PQ is a wireless communication device that detects toilet occupancy. The device has a built-in PIR sensor (pyroelectric human body infrared sensor) to detect whether someone has entered; the detected data is transmitted to other devices through the wireless network, and the SX1276 wireless communication module is used.
The R718PQA is a wireless communication device that detects toilet occupancy. The device is equipped with a reed switch sensor for detecting the switch status of the door; a built-in PIR sensor (pyroelectric human body infrared sensor) to detect whether someone is in the toilet. Two detections are established at the same time to determine if the toilet is occupied. Through the wireless network, the detected data is transmitted to other devices for display, which uses the SX1276 wireless communication module.
R718VA is a device to detect the status of toilet water, hand sanitizer level, presence or absence of tissue.
