The MTH01 is a MCU based temperature and relative humidity sensor module,comprising a SPI interface (master mode)for direct temperature and humidity read out. The digital output is pre-calculated and no extra calculation is required. The system applied two sensor elements: NTC type high precision temperature sensor and a resistor type relative humidity sensor from Japan. With a very unique and patented relative humidity calculation algorithm, the system can assure accurate relative humidity output through fine tuned temperature compensation mechanism.Thus very high accurate reading of humidity in the full temperature range (0-50C) can be assured.
