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 ...

Everything always looks good on paper (and in its seller’s description), so I plugged my module into an Arduino Prototyping Shield for a quick/lazy evaluation using an Arduino Uno. If you have played ...

With a standard old HC-SR04 ultrasonic sensor, an audio module and a servo to drive a custom gauge needle he’s made a device which can warn people around you if they’re too close for comfort.

Inside the 3D printed enclosure is an Arduino Pro Mini, a HC-SR04 ultrasonic sensor, ... With a standard old HC-SR04 ultrasonic sensor, an audio module and a servo to drive a custom gauge needle ...

Watch the demonstration video below to learn more about Zola’s project which uses TX and RX transducers desoldered from an HC-SR04 module, together with a pair of Arduino Uno development boards ...

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 ...

The module, the IA-UWM-2-GP30-DN20 from Chinese metering equipment manufacturer iESLab, is based on the ams TDC-GP30 ultrasonic flow sensor chip. The TDC-GP30 performs precise timing measurements and ...
