Pros: + cheap! + accurate up to 6 meters, can detect really small movements when tuned properly
+ comes with the distributor (white part)
+ perfect for projects, home automation, security etc.. Cons: - not really sure about the knobs, another is time and think another is sensitivity.. time you can calculate with your arduino (for example) and the sensitivity ... Read more

No cons ... Read more
Very good product, easy to use. Detects humans outdoor located, in 15 meters distance at least. It can detect a cat in two meters. You can connect this product straight away to many projects, works great with arduino etc.. output is 3,3 V.
Easy to trim sensivity and delay. At least the capacitors should be SMD, this instrument is raher big, you see.... Read more
Easy to use with just only a transistor (or other) needed to amplify, buffer the output.
Include the control over sensitiveness and time.
Very good range and sensitive even at "middle" setting. Even a centimeter of hand movement can be detected at range of 3 meter.
Very wide angle of detection, don't need to point directly at target position ... Read more
