  • the automatic sensor: to enter the sensor output range is high, people leave the sensor range of the automatic delay off high, output low.
  • the photosensitive control (optional, factory is not set) may set the photosensitive control during the day or light intensity without induction
  • the temperature compensation (optional, factory is not set): In the summer when the ambient temperature rises to 30 ~ 32 ?, slightly shorter detection range, temperature compensation can be used as a performance compensation

This is a very neat little module, built on a good quality PCB, and works better than I expected. I did a web search for "HC-SR501 pir datasheet" and found some helpful information about using this device. At its maximum sensitivity setting, the module will detect human body motion even beyond its specified 7 metre range, provided that the motion is ACROSS the sensor's field of view. Detection range is greatly reduced when moving directly towards or away from the sensor. The data sheet that I found on the web explained the reasons for this. In my opinion, mounting the module could be a little tricky; two M2 mounting holes are provided on the PCB, but thread-stock below M3 tends to need a specialist supplier, and although M3 pillars are commonly available, I have yet to find any M2 pillars. The clearance between the mounting holes and the PCB conductors is very small, so care will be needed when incorporating this module into a housing. However, these are minor drawbacks; the module is good value for money, and works well if used correctly.

Such a great item. Very easy to wire up and it worked so easily. The only down side is the distance and sensitivity is not the great, but for a cheap item, it works better than expected for the price.

Three connections to TTL or lower voltage supply, with one line changing when sensing movement. Two trimmer pots set sensitivity and response.

Very simple to put into use !

Very cheap. Comes direct from China so takes a bit of time in the post. Haven't got round to using it yet due to lots of other projects but seems to be well made.

Handy little module which works very well once you work out what the pots are doing. It is basically a standalone alone module needing no other electronics apart from some power (5-20v). Once power is applied, it generates an output which can drive an led or other circuits to do other things. Only gripe is that to fit easily into a breadboard, the 3 pins are best bent to an angle. Cheap and well made. Quick delivery too.

OK, but the links for triggering modes are just solder pads not pre-fitted links. Therefore it isn't as user friendly as other suppliers as it needs my soldering iron and magnifying glass once I figure out which way to link it. (Need to find cct diagram as well on the internet as there's nothing in the packet

Arrived in an anti static bag inside a padded envelope, the item is exactly how it was described, very nice build quality. I'd recommend this product to other raspberry pi and arduino fans.
