Conclusion:

With this sensor you can detect more than just movements. He also has a lux meter, temperature meter, UV meter and shock sensor built in. This makes it unique because other motion detectors do not have this. You often have to buy several sensors. Another unique feature is that it can be supplied with power via USB, which saves on changing batteries again. In addition, you can set the update times very low so that the values ​​come in faster and you can therefore respond better with a scene.
The whole looks neat and will not stand out in your interior. He is really super small with his 42mm. You can provide it with 2 CR123AA batteries, this saves changing again. The sensor can be hung by means of the supplied brackets which can be attached with screws or a double-sided sticker. There is also a variant available where an extra bracket is included so that you can build it into your ceiling (just like halogen spots). Finally, we mention the price of € 69.95, which makes it slightly more expensive than other motion sensors. But this more price is made up for by many unique features.
