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 ...

Buy arduino, buy sound shield, buy distance sensor shield, plug into each other, burn example code, stuff components inside box. Not only is this not a hack but he might as well have just bought a ...

Ultrasonic sensors at the bottom of each tube measure the distance to the weights. ... The sensors cost a dollar. The other parts – PVC pipe, weights/pulleys, Arduino and the Radio key fob ...

An Arduino polls the ultrasonic sensors and provides feedback via the boxes. This completely frees up the user's hands for other tasks. Advertisement. While the prototype has a ways to go, such as ...

This one is an unusual smart home project, potentially - how to monitor a fish tank’s health with an AI-enabled ultrasonic sensor system. The detailed project is highlighted on Hackser.io and features ...

Ultrasonic sensors are covered within special acoustically transparent plastics. How They Work. The design of a robotic ultrasonic system is similar to collision avoidance and parking systems in cars.
