Hi,
I need a motion sensor which can detect motion in the range of 6" to 18" inches. (No more or less). If it is a 360 degree then it will be perfect. I saw the following motion sensor and I want to know that can it be adjusted for the above range. Thanks

Hello.
Unfortunately we don’t have any sensors that can sense a full 360 degrees around.
You’re probably not going to find any sensor that only reacts to motion only between 6" and 18" either, but you could connect a sensor (or multiple sensors that look in different directions for a 360 degree view) to a micro controller and write a program that ignores any motion > 18" or < 6" from the sensor.
