The topmost part of the PIR sensor consists of a lens with concentric grooves carved into the plastic. These are called Fresnel lens. The contours on this plastic helps in gathering parallel light ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

Passive Infrared (PIR) sensors are electronic devices that detect motion by sensing infrared radiation emitted by objects. Every object with a temperature above absolute zero emits infrared radiation.

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

Arduino has announced the launch of its Oplà IoT Kit, described as an open programmable IoT platform. It aims to simplify the building of custom IoT devices, with support for cryptographic control ...

Are you tired of relying on traditional motion detection systems that require complex wiring and bulky hardware? Then it's time to upgrade to an IoT-based motion ...

The Bee Motion S3 is an ESP32-S3 WiFi and Bluetooth IoT board with a PIR motion sensor beside the more usual I/Os, Qwiic connector, USB-C port, and LiPo battery support. It is at least the third PIR ...

Makers and electronic enthusiasts looking for inspiration for their next project maybe interest is in a new build created by Robert John. Using the Arduino Oplá IoT Kit and Arduino Cloud, Robert has ...
