DF555 Ultrasonic Level  Sensor

DF555 ultrasonic level sensor can measure the distance from sensor to the surface of liquid/solid and send data to cloud server via built-in IoT wireless module. Then user can monitor the level remotely.  Widely applicable for the close container or open container, or even the river. Furthermore it can calculate the volume based on the dimension of container (platform features).
