By reading different values from the sensor, we can detect if is it light , dark or a value between them. Another element that we are going to use on this experiment is Piezo Buzzer.

This paper proposes the use of Rochelle salt (KNaC4O6.4H2O) as a piezoelectric sensor for efficient smart energy saving systems. The piezoelectric properties of Rochelle salt tested for different ...

The piezo disc sensor head (see above circuit) will keep A0 of Arduino at 0 V until it’s disturbed. Once the hardware setup is completed, upload the code, and hit the sensor head with your finger. In ...

Piezo-Buzzer with a Proximity-Controlled Tone For-fun experiment with an Arduino UNO, where a passive piezo-buzzer’s pitch is controlled by an ultrasonic sensor (HC-SR04).

This project proposes developing a compact, wearable Morse code glove with piezoelectric sensors to detect finger taps. The glove sends signals to an Arduino microcontroller, which decodes the Morse ...

Differences in the design and placement of sensors used can give different vibration measurement results on the transformer. This research designs piezoelectric accelerometer sensors to detect ...
