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 ...

About project: This simple project demonstrates how to work with PIR sensor. For this example is used motion sensor with built on chip BISS0001. How it works? When Sensor sense motion onboard LED goes ...

simple circuit with an Arduino and PIR motion sensor that can detect movement. An LED will light up when movement is detected. Introducing the PIR Motion Sensor The PIR motion sensor is ideal to ...

Motion sensor circuit Fig. 1: Circuit of motion sensor for security light. The working of the circuit is simple. When you power-on the circuit after assembling all the components including the CFL, ...

The BOM on [Jeremy S Cook]’s build is extremely short – just a PIR sensor and an optoisolator, with a battery, a plug for the camera’s remote jack, and a 3D-printed bracket.

It’s a simple little hack, but [Lochie] is pleased with it, and we imagine that he likely has a long list of other creative ideas in mind for his newly discovered PIR sensor.

This idea describes a white- LED (WLED) driver circuit controlled by a simple ambient light sensor (ALS). A typical application would be a brightness control for cell-phone backlighting. On a very ...
