Water Level Sensor Working Principle
The resistance will be a function of water level impurities in the water and time.
Water level sensor working principle. By this the change can be observed in the speed of the motor. Water level sensor pinout. This water level controller will use two components the ultrasonic sensor and relay board. It just detects if water is there.
There is a special program that executes the sensor. The less water the sensor is immersed in results in poor conductivity and will result in a higher resistance. The sensor produces an output voltage according to the resistance which by measuring we can determine the water level. The distance for the motor to turn off and on needs to be specified.
It will vary wildly between open circuit for distilled water to a few kilo ohms or less for salty water. Water flow sensor consists of a plastic valve from which water can pass. When water flows through the valve it rotates the rotor. Ultrasonic level sensor working principle.
Take a look at the ultrasonic level sensor working principle above. 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. A water rotor along with a hall effect sensor is present the sense and measure the water flow.
