This is a powerful yet compact PIR sensor. It packs some extra features, as light sensor to enable night only operation if needed, sensitivity potentiometer for fine adjustment, it can provide motion detection signal to a microcontroller or even drive a small load directly connected to its output and even has an extra pin that allows to disable the sensor to save power (optional use).

I went with shopsimplytronics because the PIR sensor looked to be better than eBay knock-offs while cheaper than what the big shops charge for it. Very satisfied with the service and the product as well. It works as expected and it feels like a high quality breakout. The documentation is an added plus. this was a positive experience and I wish the store had more products to choose from.
