Introduction
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
major diameter D
≥11
mm) 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 .
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.
