The STS35 temperature sensor from Sensirion gives a fully calibrated, linearized, and supply-voltage-compensated digital output and has an outstanding accuracy of up to ±0.1℃. It provides an operating temperature range of -40-125℃ and up to 1MHz I2C communication rate. Besides, the sensor can heat up itself to dehumidify the chip, which means it can function properly in a certain level of humidity.
