Involvement:General (knows how to use it) - Ownership:1 week to 1 month
It's very good and easy to use. It's very sensitive and can work within 2 meters as far as I've tested it.
Not a con, but it's not ideal to use in small spaces. It would be ideal to put it in a room and it will trigger whenever someone goes inside. Because it measures the change in the background temperature to sense a moving object.
It's a cool tool and handy in a lot of projects. Also, it is very easy to use, in Arduino it's as simple as checking if the digitalRead of the sensorPin is HIGH. And there are a lot of online tutorials for it.
