PIR sensors are experiencing sustained growth in 2026 driven largely by the expansion of smart home technology and building automation.

The size and price of the ESP wifi modules have quickly made them into one of the preferred building blocks for IoT devices. Unfortunately they are not particularly well suited for very low power ...

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.

The LS6506R is a pyroelectric infrared (PIR) sensor interface IC that is designed to drive a latching relay. However, the device can be used in a wall-switch configuration (no Neutral available) to ...

The main principle of the circuit is to provide security using PIR sensor. This can be used in the museums to protect the valuable things and also in defense applications to detect the humans in war ...
