Moderately priced Passive Infrared PIR Sensor modules are now widely available. By using these readymade and pre-configured PIR sensors, even an average electronics hobbyist can construct his/her own ...

Rust library to interact mainly with PIR motion sensors on Raspberry Pi platform. This lib was tested mainly on HC-SR501 motion sensor on Raspberry Pi 400 and Raspberry Pi 4B and it's widely used at ...

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 ...

In the microcontroller era today, Arduino is more than just a tool to accomplish hobby tasks. There is actually a close relationship between microcontroller technology and home security, since you can ...

[ladyada] has a freshly-published and amazingly thorough tutorial on passive infrared (PIR) motion sensors. Most often seen in security floodlights and automatic doors, in creative hands these sensors ...

A PIR (passive infrared) motion sensor is a device that detects physical movement within its field of vision by sensing changes in infrared radiation. This sensor works on the principle of detecting ...

Smart Bee Designs’ Bee Motion is an ESP32-S2 board with a PIR motion sensor, some GPIOs for expansion, and promising over a year of battery life under the right circumstances. If the name “Bee Motion” ...

(Passive InfraRed sensor) A device used to detect motion by receiving infrared radiation. When a person walks past the sensor, it detects a rapid change of infrared energy and sends a signal. PIR ...

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 ...
