THE 5-SECOND TRICK FOR WATER LEVEL SENSOR

Observe The sensor contains a Doing work voltage number of three to 5V and works by using around 20mA of present-day. So, you may feed the sensor by using a three.3V Arduino pin.Ultrasonic sensors emit high frequency sound waves within the transducer. These sound waves then reflect off the liquid surface you are trying to measure.#define sensorPin
