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 ...

I try to make the PIR sensor module without using the commercial IC which has all the functionality such as normal-mode, re-triggering and turned on only at the dark environment. This is very hard to ...

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

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 ...

HOLTEK announced its new PIR module series, the HT7M21x6, specifically designed for PIR product applications. These all new PIR modules come complete with a fully integrate PIR sensor, Fresnel lens, ...

Wireless data transmission enables many applications (e.g., in the field of home automation). However, the communication must be robust and reliable. This nRF24L01+-based PIR sensor project is a basic ...

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 ...

Abstract: Pyroelectric infrared sensors (PIR) are excellent devices to detect human/animal presence with a small form factor and rugged design, for cost-effective surveillance. They are widely used to ...

This paper presents an experimental setup to measure the horizontal centering error of a pre-built pyroelectric infrared (PIR) sensor module, in which a dual-element ...
