HC-SR501 Human Infrared Sensor Module Including Lens
A part of the review has been auto-translated.
Thankfully this has a diode to prevent connecting it backwards. The diagrams I found online were incorrect. The pcb labels are under the plastic dome, so double check by removing it before connecting. Other than that, it works.
Perfect project IR sensor module ... slightly larger than I expected (size of thumb nail) but well constructed, and with easy setting, so packed with functionality.
It is excellent, it looks of very good quality the product. I came just like I should be, no problem.
