🚀 Elevate Your Projects with Precision Motion Detection!
The DEVMO 2PCS Pyroelectric Infrared IR PIR Human Motion Sensor Detector Module HC-SR501 is a versatile and adjustable motion sensor solution, designed for seamless integration with Arduino projects. With a wide voltage range and customizable trigger methods, this module is perfect for both hobbyists and professionals looking to enhance their automation systems.

Slightly different than shown, but still good HCSR501 sensors
The modules I received are virtually the same as the ones shown in the picture. Not sure if this is a newer design because my older PIR sensors look like the blue PCB ones. Notably these are lacking the electrolytic caps that are sticking out on each end on the blue PCB version, so these are superior for breadboards. Still tunable the same way, identical pinout, basically a dropin replacement. So I guess I would consider this a happy surprise. I tested both out with an ESP32 and an LED and although I had to jack up the sensitivity (I always have to with these modules), they do work well.

Handy Way to Detect People
These modules are easy to use and adjust and are a great way to add people detection to my projects. The interface is simple and uses a single binary GPIO pin on the microcontroller of choice. The modules appear to be pretty accurate as well (no false alarms).
