How to Use a Piezoelectric Sensor?
To use a piezoelectric sensor is the easiest task, just connect the positive and negative terminal to your circuit and press the top of sensor.
By pressing, due to mechanical pressure it create voltage at output which is further feed to the circuit.
You can simply connect a LED to the piezoelectric sensor, as shown in the circuit below.
Whenever you press the sensor the LED will give a flash.
