CatDogFoxBot #4 : GridEye Sensor is Connected and Working

12 Jul 2019

I have now make the I2C connections between the GridEye sensor and the Nano. The specific GridEye sensor that I purchased did not seem to have any accompanying documentation, although it was claimed there was some on the suppliers website but I could not find it. So, I decided that as it was a breakout board that most simple GridEye breakout boards would be pretty much the same so I used the Adafruit documentation and library.

 

There was one problem in that the GridEye is a 3.3V device but the PCB I have just says Vin. After a close look at the PCB there does seem to be a voltage regulator so assuming they would have put 3V instead of Vin if there wasn't a regulator I connected it to the 5V supply from the Nano. The other I2C connections were straight forward

 

SCL connects to A5 on the Nano

SDA connects to A4 on the Nano

 

Next I downloaded the Adafruit library and added it to my Arduino IDE (really easy and simple - once I had found the ZIP file on the Adafruit web page) and then loaded the AMG test programme provided in the examples (called amg88xx_test) which just checks that the I2C link is working properly by reading the GridEye internal thermistor. This was working correctly so I then downloaded the pixels-test programme from Examples which transfer the 8x8 array of temperature measurements, once every second. This also worked first time and it may be possible to see some of this data in the video below.

I will now have to start thinking about how to process the thermal array data so that I can (or might be able to) detect cats at night.

    Looking good!

    Dubbie, Great that you are getting data off your GridEye sensor. Those things are pretty nice, I might have to get me some of those to play around with. Keep up the good work! Gene

    Gene, At present, it does seem as if the GridEye is an interesting sensor. I'll have to see if I can make use of the data that it provides as the field of view at 60 degrees is pretty wide. Any cats more…

    This looks like a very interesting sensor. The much narrower Y angle of view at 6 degrees is much better than the sensor I am using which is 60 degrees, so it would have a much longer range. It does have some drawbacks, the datasheet indicates it should not be used outdoors, it has a much more limited temperature range (0 to 50 degrees) and is quite costly considering it only have 8 sensing elements. Still, I might get one just to try out.

    Omron do a single row 8-pixel sensor (D6T-8L-06) which would give you a narrower 6 degrees field of view on one axis. Given that you are sweeping the sensor with the stepper motor then it may be worth considering.

    I did wonder about using something like this but they tend to be made from glass which filters out some of the infrared used by the sensor and proper infrared lenses cost a fortune.

    This is new technology to me and I will look forward to learning more as you develop it. I wonder if you can narrow the field of view with a collimator?

    Hi Dubbie,

     

    Awesome project : ) It's great to see Grid-EYE being used, it's a very cool sensor!
