Review on π Highly Efficient DIYmall HC SR501 Motion Infrared Arduino for Enhanced Arduino Projects by Peter Hallett
Tried two of the five do nothing even though I worked with them for an hour
Remove the protective plastic bubble to see which pin is GND, 5V and OUTPUT. I connected them to my Arduino. Set the pin as INPUT and again as INPUT_PULLUP and it will never move from HIGH. I've searched the web for clues, tried the ones I found, but these things seem useless. First Arduino sensor/component/something in 5 years that was NOT BAD out of a foil bag. Say hello to my little trash can.
