Here is one simple circuit of a general-purpose white LED security light with Passive Infrared (PIR) Motion sensing mechanism. At the heart of the circuit is a PIR sensor module SB0061. SB0061 is a ...

This project uses an Arduino board with a PIR motion sensor to detect movement. When motion is detected, an LED lights up and a buzzer sounds. It's ideal for simple security systems or motion-based ...

simple circuit with an Arduino and PIR motion sensor that can detect movement. An LED will light up when movement is detected.

TK has combined a PIR with an Arduino to create a smart safety light for the house or workshop. Follow along as this gets built out into a more extensive project.

RCWL 0516 Module The RCWL-0516 Microwave Radar Sensor module has been designed as an alternative to the common PIR motion sensors widely used in burglar alarms and security lights. Like the PIR Sensor ...

Using motion detectors and an Ardunio you can add a little extra wow to your Halloween displays this year. This article covers the circuits and the code to make that happen.

Connections for arduino based door opener circuit are shown in the above diagram. Here a PIR sensor is used for sensing human motion which has three terminals Vcc, GND and Dout.

The motion detector will detect the motion of the people or objects and give the appropriate output according to the circuit. There are some motion detectors which will use different technology and ...
