MLX90614ESF-AAA Infrared Temperature Sensor 90° FOV


Vendor's Description: 

The Melexis MLX90614ESF-AAA is a high-accuracy, high-resolution, non-contact thermometer with a 90-degree field of view. It has a measurement resolution of 0.02°C and is factory calibrated for a wide -70 to 380°C object temperature range. The sensor uses an SMBus (I²C-compatible) digital interface and can be configured to output a customizable 10-bit PWM output for continuous readings.

Any ideas on how to connect this thing to a PICAXE project board (28X) and programming it in Basic? I'd like it to recognise if something around human body temperature enters the sights.

This looks like an interesting possible replacement for the expensive TPA81 sensor. It's got a less precise field of view -- the output is the average temperature of the entire 90* field of view, whereas each of the TPA81's pixels sees 5.12* x 6*. So it'll probably be hard to pick out a human body out of the background heat of a room unless you're close enough that the human fills most of the 90* FOV. But it's only $20, whereas the TPA81 is $100+, so it might be worth playing with.
