Using motion ... sensor to block any heat signatures approaching from the side. Of course you can use multiple sensors and outputs to trigger different effects depending on your needs. The Arduino ...

Arduinos are great microcontroller boards with plenty of interesting features, but they can't do much without additional components. There are loads of unique sensors available on the market for ...

Historically, we’ve used IR and ultrasonic sensors but [Makers Mashup] decided to use an ESP32-Cam as a motion sensor in his latest ... a 3D-printed enclosure to make the hardware assembly ...

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 ...

Like the Arduino ... connected motion detector that [Eric William] has come up with. With just a Wemos D1 Mini, a standard PIR sensor, and some open source code, you can create a practical self ...
