The sensor’s microprocessor calculates the distance and converts it to a level indication, volume measurement, or a rate of flow. GND pin needs to be connected to GND(0V) 3. Setting a maximum and minimum detection distance simply causes the sensor to ignore any echoes outside of that range. They are also widely used in water treatment applications for pump control and open channel flow measurement. Because the speed of sound is a constant, under fixed atmospheric conditions, the time from the sound burst to the return is measured and translated into a distance. If you leave it on high all the time, it will wear down faster, just like a speaker can be blown out by too much volume. The softness of light powders will absorb most of the sound signal, while dust will dissipate the signal in the air before it can return to the sensor.
