The TSYS01 is a Temperature Sensor provides factory calibrated temperature information. It includes a temperature sensing chip and a 24 bit. The essence of the digital 24-bit temperature value and the internal factory set calibration values lead to highly accurate temperature information accompanied by high measurement resolution. The TSYS01 single chip, versatile, new technology device can be interfaced to any microcontroller by an I²C or SPI interface. This microcontroller has to calculate the temperature result based on the ADC values and the calibration parameters.
