Water level sensor pinout.
Water level sensor working principle.
By this the change can be observed in the speed of the motor.
It just detects if water is there.
That is not a water level sensor.
There is a special program that executes the sensor.
This water level controller will use two components the ultrasonic sensor and relay board.
Take a look at the ultrasonic level sensor working principle above.
A water rotor along with a hall effect sensor is present the sense and measure the water flow.
The water level sensor is super easy to use and only has 3 pins to connect.
The distance for the motor to turn off and on needs to be specified.
The less water the sensor is immersed in results in poor conductivity and will result in a higher resistance.
The resistance will be a function of water level impurities in the water and time.
The water level indicator includes a simple mechanism which helps to detect and indicate the water level in an overhead tank or any other water container the sensing is done by using a set of nine probes which are placed at nine different levels on the tank walls with probe 9 to probe 1 placed in increasing order of height common probe i e.
Water flow sensor consists of a plastic valve from which water can pass.
Ultrasonic level sensor working principle.
It will vary wildly between open circuit for distilled water to a few kilo ohms or less for salty water.
