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.

Built an infrared motion detector using an NE555 timer IC for AC load control and an IR sensor module for sensing motion. Some key components of the circuit are a BC547 NPN Transistor which functions ...

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 ...

Product Features. 💎【HC-SR501 PIR Motion Sensor Module】: human body infrared motion module is an automatic control module that based on infrared technology, with high sensitivity, strong ...

Last year, I took a look at some mostly low-cost passive infrared (PIR) motion sensor modules. Then recently, I became more aware of cheap microwave radar motion sensor modules. The popular version of ...

This paper deals with the description of the development and design of a sensor with wireless data transmission for detecting the movement of people. As part of the development of the sensor, the ...

STMicroelectronics is launching a novel human-presence and -motion detector to enhance security systems, home automation equipment, and IoT devices that typically use passive infrared (PIR) sensing.

I have a Nikon D7100, but I don't know of any way to trigger video capture based on an external IR motion sensor. I also have a variety of Reolink cameras with marginally better IQ, ...
