Stay tuned for that do it yourself project. Below is the Arduino Sketch used to test the JSN-SR04T ultrasonic distance sensor. This sample code does not require a library. #define trigPin 12 // Trig ...

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 ...

While early scientists and inventors famously underestimated the value of radar, through the lens of history we can see how useful it became. Even though radar uses electromagnetic waves to detect ...

With a standard old HC-SR04 ultrasonic sensor, an audio module and a servo ... sound like for anyone who has a bunch of these little Arduino-compatible modules lying around and has probably ...

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 ...
