Every smart home owner is likely to be familiar with “passive infra red” (PIR) motion sensors as they’re an easy way to start off making a home a little smarter They’re quite distinctive too, with the ...

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) ...

ABSTRACT: This study investigates the optimization of Fresnel lens designs using Zemax software, with a focus on minimizing beam divergence by controlling the output spot diameter on the image plane.

The library gives control over up to 16 parallel working PIR devices over I2C. The idea for this library came up in a discussion about how to fully cover an area with PIR sensors without blind spots ...

As radar technology continues to advance, it offers an increasingly broad range of capabilities, making it a viable alternative to traditional passive infrared (PIR) sensors. With radar’s enhanced ...

STMicro STHS34PF80 is a new IR sensor designed for IoT and Smart Home devices requiring motion and/or presence detection that offers an alternative to traditional passive infrared (PIR) sensors and is ...

Designed by Smart Bee Designs, the tiny Bee Motion Mini combines an ESP32-C3 wireless RISC-V SoC with a PIR sensor for motion detection reporting over WiFi, Bluetooth LE, or Bluetooh Mesh. The board ...
