SHT85 Details

Sensirion recommends a layout with a ground plane underneath the sensor, and a minimum of 1 mm clearance around the sensor to ensure accurate humidity and temperature measurements.
The SHT85 has a high current consumption during measurement, so it's recommended to use a voltage regulator with a high current capability, and to add decoupling capacitors close to the sensor to filter out noise.
Sensirion recommends a two-point calibration procedure, where the sensor is calibrated at 30% and 80% relative humidity, and at 20°C and 40°C temperatures. The calibration data should be stored in the microcontroller's memory.
To ensure accurate humidity measurements in high-temperature applications, it's recommended to use a thermistor or a temperature sensor to compensate for the temperature effect on the humidity measurement.
The SHT85 uses a proprietary 2-wire serial interface, and Sensirion recommends using a clock frequency of 400 kHz to 1000 kHz, with a data transmission rate of 100 kbps to 400 kbps.
