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.

The PIR (Passive Infrared) sensor is the heart of our burglar alarm system using pir sensor. Whenever there is any body movement, the voltage at the output pin changes. Basically, it detects the ...

This project demonstrates the basics of using the ESP-IDF component "mjd_hcsr501". The component supports various PIR motion sensor models: HC-SR501 PIR motion sensor module. MH-SR602 Micro PIR motion ...

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 ...

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 ...

(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 ...
