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 ...

Now, the venerable ultrasonic sensor joins the gallery of classics given a size change treatment, like the 555 timer we’ve seen two different takes on, or perhaps that one Arduino Uno.

Ultrasonic sensors at the bottom of each tube measure the distance to the weights. The weights sit in static equilibrium, so they serve the purpose of keeping the string taut without negatively ...

Sometimes, the best Arduino projects are the most ridiculous. Case in point, this motion-detecting squirt gun. The idea is simple: when it detects motion, the spray gun activates.

The Arduino IoT Cloud provides a low-code approach that enables users to collect, graph and analyse their sensor data, trigger events and fully control their devices. The IoT Cloud provides a full ...

In this project, students will design and prototype a novel wearable sensor for continuous physiological monitoring (e.g., heart rate, blood pressure, glucose, etc.). Besides the conventional ...

This project is to prototype a set of self-powered (such as piezoelectric, thermostat, solar, etc) embedded sensor systems for pervasive computing. A tangible exam is a body-temperature powered motion ...
