## Questions & Answers

**Q: can these be hooked in a circuit without an Arduino**
A: I should think so. You just need a way of reading the values coming from the sensor to detect motion.

**Q: range please - how far away can it be from the surface that you are measuring?**
A: Depends on the sensitivity setting. I have had no problems in the 2 to 3 meter range which is perfect for my uses. Also, this is an infrared sensor that senses motion, so if your surface is stationery, you might consider an ultrasonic sensor instead.

**Q: What is the field of view at 20 ft.?**
A: It's pretty good, full range in 2 more feet

**Q: What are the dimensions of this?  Specifically looking at the depth of the white dome and size of the white square.  Trying to hide in woodworking.**
A: From the dome top to the top of the square is .5"
The square is .913" on a side
