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.

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.


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.
