In the water level sensor schematic, the common probes connecting the underground tank and the overhead tank to +9V supply are marked ‘C’. The other probe in underground tank, which is slightly above ...

Circuit diagram: The circuit described has been used to maintain the level of water in the header tank within prescribed limits. It controls a 3HP submersible bore pump which has a high starting ...

You should set the sound to the most irritating level possible. Gate IC1d is used to boost the amount of power than can be pumped into the buzzer. It inverts the output signal from IC1c to double the ...

Ultrasonic sensor will detect the level of water then it will send the data to Pump. This project can help to save water. We can apply this whole setup in our home. Project Used Hardware. Arduino pro ...

The following image shows the circuit diagram for interfacing the Contactless liquid level sensor with Arduino. Connections are pretty simple and only a few wires. Connect the VCC and GND of the ...

Microcontroller based Water Level Controller-cum-Motor Protector Circuit. Fig. 1 shows the circuit of the microcontroller-based water level controller-cum-motor protector. It comprises operational ...

Fig. 1: Circuit diagram of transmitter unit of the wireless water-level indicator Fig. 2: Circuit diagram of receiver unit of the wireless water-level indicator. Bases of T1 through T4 are connected ...

This simple water level indicator will activate an active buzzer (e.g. BeStar BPT-23CX ) in order to make a noise when a certain level of water is being reached. Because the water sensor and the ...
