In this experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

If you are engaged in an energy harvesting project that involves piezo sensors powered by vibrations, you might want to check out the most recent issue of Applied Physics Letters (Applied Physics ...

Piezo comes from the Greek word “piezein,” which means “squeeze” or “apply some pressure.” Whether they take form as a transducer or sensor, piezo components all operate as the result of some degree ...

Haptic technologies recreate touch sensations by applying a combination of force, vibration and motion to the user. Haptic technologies are also thought to be a $12.8 billion industry by 2022. In ...
