Uses the I2C interfaceTypical humidity accuracy of ±2%Typical temperature accuracy of ±0.3COperates from 0 to 100% humidity but this sensor isn’t recommended for harsh environments where it could come in contact with water (such as rain)3.3V sensor – use inline logic level converters or 10k resistors to limit 5V signalsOnly one HTU21D sensor can reside on the I2C bus at a time
