The R72611 is a wireless communication device that detects the depth of a liquid. The R72611 detects the depth of the liquid in the container. The main part and the sensor are connected via the RS485 interface, and the detected data is transmitted to other devices through the wireless network. The wireless communication method conforms to the LoRaTM protocol standard.
Note: Different types of liquids have different requirements for the sensor, so it is necessary to select the sensor according to the type of liquid.
