Best Motion Sensor with ST? (2016, now out of date)

There’s no one best sensor, different ones will be a better fit for different use cases. And of course some people want to keep the cost down and are willing to give up features to do so.

The following thread has good discussion of the various features which can help you decide whether you need one of the more expensive sensors or not.

As far as inexpensive ones, if you are in the US, it’s hard to do better then the iris brand from Lowe’s, especially when they are on sale. If you are in the UK then Orvibo is a good bargain brand, but it has fewer features than some of the others. In particular, no temperature sensor.
