The sensor is used for determining the liquid's level in the vessel. It is powered with the voltage from 2.0 V to 5.0 V. The output is an analog voltage which increases its value along with the depth of immersion of the probe which makes it compatible with most of the development kits, for example,Arduino. The device works in the range of up to 48 mm.
The sensor has an analog output that should be connected to the pin of the A/D converter (analog input inArduino). This will allow you to measure the proportional voltage signal to determine the liquid's level.
|VCC||Supply voltage from 2 V to 5 V.|
|GND||The ground of the system.|
|AOUT||Analog output with the voltage proportional to the liquid's level.|
