Product description: Mini PIR motion detector HC-SR505

PIR type sensor allows to detect motion, used to detect human presence in rooms in alarm and lighting systems. The sensor is powered by a voltage from 4.5 V to 15 V, has a range of up to 3 m. Detection of an object is indicated by a high state.

Digital output allows to connect sensor with any runtime kit e.g. Arduino, STM32Discovery or minicomputer Raspberry Pi. The outputs are goldpin connectors (raster 2.45 mm), which allow to connect the sensor with wires.

Product compatible with Arduino

How to use

Power supply (4.5V to 15V) should be connected to the external pins marked + and - on the picture below. Detection of an object, in the field of view of the sensor, is indicated by a high state appearing on the OUT pin.

Good study aid.
Dariusz K. 05.11.2021 Confirmed purchase Translated review
Does the job. It would be nice to write somewhere in the view that the high signal after motion detection (from the middle pin) remains +/- 8 seconds. Besides, the product is nice, tiny and works. I am happy, but if someone wants to make a mechanism for recording the environment after motion detection, I recommend the arduino webcam plus motion applications / service which by default only saves recordings in which motion has been detected based on the images. A lot of things can be calibrated there and it seems like a better option than this sensor. Thanks and regards.
