The information of sensor reply will be directly reported to the gateway, and displayed in the interface on the gateway. It uses SX1276 wireless communication.
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.
R718T is a Wireless Push Button Interface.
It can connect with an external push button and detect whether the external button is pressed.
The Wireless 2-Input Push Button Interface allows a notification signal to be sent when connected
push button is pushed. When someone is in danger and needs emergency assistance, press the
emergency push button device; R718T2 immediately sends an alarm message to the gateway.
R718TB is a push button which detects the signal of the device.
R718VA is a device to detect the status of toilet water, hand sanitizer level, presence or absence of tissue. This device is connected with a non-contact capacitive sensor can be mounted to the exterior of the container, without direct contact with the object to be detected, which may detect the current water level of positions mounted, or the presence or absence of liquid soap or toilet paper; the detected data is transmitted to other devices through the wireless network. It uses the SX1276 wireless communication module.
R718VB can detect the toilet water level, hand sanitizer level, presence or absence of toilet paper, it may also be applied to non-metallic pipes (pipe diameter D≥11MM) liquid level detector. This device is connected with a non-contact capacitive sensor which can be mounted to the exterior of the container, without direct contact with the object to be detected, which may detect the current position of liquid level, or the presence or absence of liquid soap, toilet paper; the detected data is transmitted to other devices through the wireless network. It uses the SX1276 wireless communication module .
The device is a LoRaWANâ„¢ device compatible with LoRaWANâ„¢ protocol (Class A). When the sensor detects the leak, it will send an alarm message to the gateway.
R718WA carries 1 water leak sensor.
It uses SX1276 wireless communication module.
