hi guys (and or girls)
does anybody have any experience with the Panasonic grid eye sensor?
from what I looked up the sensor has three outs, are they analog or digital?
also is there any code that could be used to tell distance of say an animal or person?

The data sheet I found https://industrial.panasonic.com/cdbs/www-data/pdf/ADI8000/ADI8000C41.pdf shows that the device uses I2C but there appear to be many versions available.
To measure distance you would use two sensors and triangulation. Look for the center of the warm blob in each sensor. The closer the warm thing the more one view will be offset from the other view.
I wouldn't be able to go off of how much "blob" its reading to measure distance from the sensor?
obviously the closer something gets to it the more red it will show right?
if I wanted to use it to turn on a light when something gets to a specified range, how would that work?
the sensor mounted to the break out board that I was thinking about using was the AMG8833
This people tracking robot project uses two GridEyes to estimate their positions.
I have been experimenting with this GridEye breakout board, which you can get through DigiKey. It works quite well.
this is the one I was looking at

Sounds like it would work by sensing the size of the blob (or just the average heat of all 64 cells). Couldn't hurt to give it a try.
If you want a sensor designed for distance measurement you can get an ultrasonic range finder for under $2 or one of the IR distance sensors made by Sharp.
yeah but for size of the sensor and angle of view. I think the grid eye has is beat in those two catagories
