THE BEST SIDE OF WATER LEVEL SENSOR

Be aware The sensor contains a Doing the job voltage choice of 3 to 5V and uses approximately 20mA of recent. So, it is possible to feed the sensor that has a 3.3V Arduino pin.Set the multimeter to DC voltage measurement manner and measure the sensor’s S pin voltage in relation to Gnd (clearly, in the event the sensor is dry, it should be zero or
