As the output goes high, the relay gets energized and the motor starts filling water in the tank. Purpose of this Circuit is to Introduce Transistor as a switch and Water level indication. This category only includes cookies that ensures basic functionalities and security features of the website. Your email address will not be published.
The relay gets de-energized and the motor gets turned OFF. This website uses cookies to improve your experience. This water level indicator project has a very simple circuit consisting of 3 probes which are used for automatic fill and cut of the water supply in tank. Find every electronics circuit diagram here, Categorized Electronic Circuits and Electronic Projects with well explained operation and how to make it procedure and then New Circuits every day, Enjoy and Discover electronics.

When the circuit is powered up for the first time the pump should be started automatically if the vessel is empty (or the level is below the required minimum level).

If the tank/container is already FULL then nothing should happen. As the HIGH level of the probe is reached, the pump must STOP. The motor remains OFF even though the water level goes below the sensor H. The motor again gets restarted only when the water level fall below sensor L. This cycle repeats every time. Use different height of insulator removed wire as shown in the circuit diagram. 
Simple Single Push Button ON OFF Relay Circuit, Simple Obstacle Identification Sensor Circuit, Simple Audio Amplifier Circuit Using TDA7052, 1 IC LED Flashing Circuit Using 555 Timer. As the water level touches the HIGH level probe, the pump must stop and should not start until the level of water reaches the low level probe. The motor remains ON even though the water level crosses sensor L. As the water in the tank touches the sensor H, the timer IC2 gets retriggered at pin6 through inverters N3 and N4 due to this the output of IC2 goes LOW.

When the water level falls below the level of sensor L, the timer IC2 gets triggered at pin2 through inverters N1 and N2 and the output of IC2 goes HIGH. It will indicate the level of water so you could see the level of water without looking into the tank. Currently you have JavaScript disabled.
