This little PIR is great because it is very easy to get up and running with. You simple provide it 5V, ground and run the yellow wire to a digital input on a micro-controller like the Arduino. It sends a HIGH signal on 5V if motion is detected. The one main setback with this device is you cannot set ... Read more
Very easy to work with, only power it and it works!! Good range and sensibility.
Can be used to make alarms, automatic lighting, and much more! Has some unpopulated pads intended to add darkness-mode capability. Maybe it should come with a pair of smd LEDs to see power and trigger. The circuit board ... Read more
a well price and reliable unit. has good sensitivity. Works well with 5- 15 V input range. made a couple of switches battery powered one and 12 volt adapter powered with the units and all works well. size is a bit to bulky for fitting / making a compact switch, but manageable. Range is bit less 4-5 M ... Read more

It's very easy to use and quite self-explanatory. Which is good, because it comes with zero documentation :) Red lead ... Read more

- capacitors and transistor on the back side are quite large
- one plastic cover of the two I ordered is not holding ... Read more
