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.

Basic motion sensing setup using Arduino, PIR sensor, LEDs, and push button for interaction & Motion-triggered alarm system with Arduino, PIR sensor, piezo buzzer, and LED alert.

Footstep Power Generation using Piezoelectric Sensors This project is aimed at demonstrating an energy-harvesting system that generates power using piezoelectric sensors placed beneath a walking ...

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 ...

Our Smart Home Using Arduino Uno R4 WiFi project is designed for home safety and convenience, integrating temperature, humidity, light, and gas monitoring. Using sensors like DHT11/DHT22, LDR, and ...

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 ...

The distribution transformer is an important tool in the power system. During operation, the transformer produces vibrations indicated on its performance. Transformer monitoring based on the condition ...

Corey Menscher, wanting to experience the kicks, movements and general in utero activities of his unborn child, developed the Kickbee, a strapped-on set of piezo sensors that monitor the baby and ...
