This project is a temperature recorder based on PIC 12F683, a serial EEPROM and a thermistor. User can set the recording interval from 1 to 256 seconds and EEPROM can store up to 32000 measurements. Thermistor linear range is between -10 °C and +40 °C. Schematic, PCB and code is available on the link below.
