    Hi,
    For temperature, sensors: LM35, LM335, TC72, DS1820, KTY18 and many more
    For humidity, sensors: SHT10, SHT11, SHT75, HS1101
    For pressure, sensors: MPX4115, MPX4250
    You could then sense and record these values with a microcontroller (PIC, AVR, dsPIC, ARM) whichever you're familiar with. You could store the values in an MMC/SD card which would give you easy access or in EEPROM memory.
