Recently, I exhausted my stock of common passive infrared (PIR) motion sensor modules and was looking for a new one to play with. I searched the web for a small type with self-contained electronics.

PIR（Passive Infrared Detection）are used to detect motion of human movement. This version has a large lens which can support long range and wide angle. 2.54mm standard connector is easy to fix it ...

The weak signal from the PIR sensor will be amplified by the first two op-amp configured as amplifiers, the amplified signal is then fed to the last two op-amp configured as comparator. The BC548 NPN ...

The module consists of: RE200b PIR sensor; Resistors; Capacitors; Operational amplifiers; Potentiometers; Switches; Buzzer and/or lamp. The characteristics of the module heavily depends on the type of ...

This motion sensor circuit based on PIR motion detector module BS1600 (or BS1700) that can be used for security or corridor lighting in power-saving mode. The 12V DC power supply required for the ...

This breadboard compatible package combines an ESP32-S2 module with a top-mounted PIR sensor, making it a turn key solution for all sorts of motion sensing projects.

Module provides integration and flexibility for passive infrared (PIR)-based motion detection applications including customer sensing, lighting control and other energy management purposes. The ...

So in this tutorial, we are going to build a Dog Barking Security Alarm using Arduino Nano, PIR Motion Sensor, and Dog Barking Sound Module. When someone gets close to your house door, a barking dog ...

[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 sens… ...

The Bee Motion S3 board with ESP32-S3 wireless MCU and a PIR motion sensor has just launched on Crowd Supply. There’s a single $30 reward on offer with the board, a lens cap for the PIR sensor, and ...
