My Initial tests (using the regulated 5VDC power supply) found it works well enough for my needs. In my quick estimation, the Grove-mini PIR motion sensor module (v1.0) is a compact and cost effective ...

At the heart of the circuit is a PIR sensor module SB0061. SB0061 is a pyroelectric sensor module which developed for human body detection. A PIR detector combined with a fresnel lens are mounted on a ...

[ladyada] has a freshly-published and amazingly thorough tutorial on passive infrared (PIR) motion sensors. Most often seen in security floodlights and automatic doors, in creative hands these sens… ...

Extremely low power consumption-10uA, Ready-to-use I/O connection options, Ceiling/wall mount device applicable, TTL open collector signal output, Built-in CdS photocell output, Superior RFI/EMI ...

This paper presents a wireless communication system utilizing a 433MHz RF module alongside human presence detection using a Passive Infrared (PIR) sensor. The system is designed to enable real-time ...
