DF200 Smart

Hand Sanitizer Level Sensor


DF200 is a Level Sensor, and automatic hand sanitizer; It can automatically sense, and periodically detect the capacity of liquid. When the level is less than the threshold, the information will be immediately transmitted to the cloud server through the built-in NB-IoT module. 

Users can observe status information remotely. Through the NB-IoT method, with high real-time performance and low power consumption.
