This video shows the working principle of the advanced ultrasonic sensors from Physik Instrumente (PI). Developed for flow measurement and bubble detection, the PI ultrasonic sensors are ...

In this module we will wire up an ultrasonic sensor and attach it to our Raspberry Pi. Using the ultrasonic sensor we will measure the distance an object is away from the sensor. The distance of the ...

The motion detector is not only used as intruder alarm but also used in many applications like home automation system, energy efficiency system, etc. The motion detector will detect the motion of the ...

Cheap stuff gets our creative juices flowing. Case in point? [Andy Grove] built an eight-sensor HC-SR04 breakout board, because the ultrasonic distance sensors in question are so affordable that a ...
