The 16x4 pixel thermal imaging module from Melexis is attracting a lot of attention because of the $150 open source/hardware iPhone thermal camera accessory described here, among other places: kickstarter.com/projects/and … -accessory
However, that design is meant to be self contained and uses Bluetooth for communications. A simple breakout for the ~ $70 sensor would be very attractive for mobile robot applications and possibly a hot selling item. The device description page is here: melexis.com/Infrared-Thermom … 0-776.aspx
The device runs on 2.6 V, so an on-board regulator and level shifters for 3.3 V and/or 5.0 V I/O (selectable) would be very handy.
