This is a very simple digital distance meter, which you can add to your water-level indicator circuit to ... It is built around Arduino Uno board, HC-SR04 ultrasonic sensor, Nokia 5110 LCD and 9V ...

Motion sensor ... Arduino Nano board. After assembling the circuit on the PCB, connect the PIR sensor across CON1 and 12V across CON2. Crosscheck the wiring/connections as per the circuit diagram.

You can also use the built-in indicator LED for debugging. Now that we have understood how a sensor works, we can connect all the required wires to Arduino and write the code to get all the data out ...
