16F88 and temperature sensor

[DynamoBen]

I currently have a switch, LCD (4-bit), DS1307, MAX232. This gives me one open, unused pin.

You might use a LM75A, and put it on the I2C bus with the DS1307, and you'll still have a Pin left.

My big concern with IC based sensors is that I will only be able to get the temp of the inside the project box everything is going into. I'm thinking I need something that I can either use remote or attach to the side of a metal project box.
