Top Positive Review

Nice PIR sensor and good price for 5. Well packaged, all 5 work. Jumpers on the High/Low setting and more doc links here would have helped earn the fifth star.

Best docs I’ve found can be found by googling “henrysbench HC-SR501 Arduino Tutorial and Manual” (Amazon won’t let me post a direct link)

Two things worth noting:
– Without any changes to jumper settings these are set in High (repeat) mode
– Running them even SLIGHTLY under 5v may cause repeat false triggers (i.e. “flashing” on/off on the output signal)

Top Critical Review

Tried 3 sensors out of 5 and none of them worked with Arduino Uno WiFi Rev2. I thought that Arduino could not supply enough voltage but measuring with a multi-meter I registered 5.01V. Two of the units brought output pin high couple of times but then no motion was detected. Remaining unit had output pin high at all times. I took one unit to work and hooked it up to a bench power supply and a scope and it behaved the same from 5V to 8V. Scope registered high at all times on the output. I did not even open the remaining units and just sent them all back. It could have been a bad luck but what are the chances that all 3 randomly picked units out of 5 would not work.

Customer Questions & Answers

Can i hook this directly to the item i want to switch? it??s dc current.
Answer:

WRCoyle is pretty much wrong on their answer. I’m assuming you want to turn electricity on to another device with this? The answer to that is no. This provides a logic output that is high when it is triggered and low when on standby. The BISS0001 chip on this has the output pin rated for 10mA and it goes straight to th??

How would you describe the range and sensitivity of these? I need to detect when motion stops in a 12×14 room of people.
Answer: It will sense any movement (heating moving paper) in a room of that size

Will these work w/ the Raspbery Pi?
Answer: Yes, this DIYmall HC-SR501 PIR sensor can work with RPI, you can check this link: http://www.instructables.com/id/PIR-Sensor-Interfacing-With-Raspberry-Pi/

If you search: PIR sensor with raspberry pi on google, you will find a lot of information

Could this be used to replace a faulty IR sensor on animated halloween props?
Answer: The pir sensor should work but the output is simply a logic level output. It will not provide much current.

Can I use this with a microbit?
Answer: Yes, you can, but you need correct cable , female dupont cable with Alligator Clip Test Lead
