I have a mlx90621 thermopile array in a TO39 can (not the evaluation board option which was way too costly). I understand it's i2c based communication, which I am trying to learn now, but any details of circuits to connect it to a Mega, or any advice generally, I would really appreciate. Thanks

I could not find the data sheet for to MLX90621, I used MLX90620, so this info may be wrong.
You are going to need a levelshifter, that sensors recommend VCC is 2.6V. and a 2.6V supply.
The Device has 2 I2C address, 0x50 for EEPROM access, 0x60 for sensor read/writes.
Do a search for UM10204, this is the I2C specification white paper.
