Sensor - What kind will make life easy?

Hi,

I'm sorry for the slightly off topic question. I have a system in place which currently has two free I/O pins free on the PIC (not UART - they are in use).

I am after a kind of sensor, preferably on a breakboard, which can be easily coded in CCS. I looked at digital temperature sensors, but the code seems very involved. Is there a simple temperature / light / barometric etc sensor which is suitable for someone just starting out in CCS.

I'd like to understand the code, so I still need it to be simple, even if there is already an existing library for it. I looked at the DS1820 but the code for this was surprisingly long and complicated.

Regards,

James

If the pins you have available can handle analog, check out the LM35 temperature sensor (output is voltage proportional to temp) or the one I am using MCP9700A from Microchip. Similar to the LM35. Both have a linear analog relationship between temperature and voltage so they are pretty easy to work with.
