Present consists of just a PIR sensor and Arduino in a 3D printed enclosure to snap onto your monitor.

In this tutorial we discussed the Sound sensor, its pinout, working, and how to interface it with Arduino. This article includes a complete Arduino code and circuit diagram along with a step-by-step ...

Arduino is an inexpensive, small electronics platform for makers. Here's how to get started with it on macOS.

The PIR library implements a class to monitor 1 or more PIR sensors. The library supports default 8 PIR sensors per object, which typically are added in setup (). It is possible to add a sensor (pin) ...

Pinout diagram The board is somewhat similar to the company’s Bee S3 board which comes without a PIR motion sensor and fewer I/Os. The Bee Motion S3 can be programmed with Arduino, CircuitPython, and ...
