Nick,

Very interesting. I like it's use to make an interactive poster. I have looked at these pyroelectric sensors for a while thinking they are good but not sure what to do with one. I like the array pyroelectric sensors so that you can get more information about what has been detected. I'm thinking of some sort of cat detector.

I tried making an interactive poster one, using Bluetooth and a set of headphones that the person would need to put on. I obtained all the parts, but never managed to get anything working. Your approach looks much simpler and easier to implement.

Interesting... A couple of things drawn from the datasheet:

maximum current 800 uA,
input voltage range 3.5 to 5.5 V
warm up time is 30 seconds max.

One of the benefits is stated to be "Excellent radio wave performance in high-frequency band" - what does that mean?
