MCP9800DM-DL2: MCU Based Temperature DataLogger


The MCP9800 Temperature Data Logger Demo Board 2, once programmed, will log temperature measurements for a predetermined amount of time until the 24LC16B is fully programmed with temperature data (i.e., 2,048 temperature readings).

Each sample uses one byte of memory. The intervals can be changed in the firmware we have provided by changing the TIMEOUTVAL variable. The firmware will take measurements for approximately 45 minutes (approx. 1 sample/sec).
