Sensirion (SHT40-AD1B-R2) Temperature and Humidity Sensor, ± 1.8% RH

Temperature and Humidity Sensor, ± 1.8% RH, -40°C to 125°C, I2C, Digital, DFN,1.08 to 3.6VProduct OverviewSHT40-AD1B-R2 is a digital sensor platform for measuring relative humidity andtemperature at different accuracy classes. The I2C interface provides severalpreconfigured I2C addresses and maintains an ultra-low power budget. Thepower-trimmed internal heater can be used at three heating levels thus enablingsensor operation in demanding environments. The four-pin dual-flat-no-leadspackage is suitable for surface mount technology (SMT) processing.Relative humidity accuracy up to ±1.5 %RHTemperature accuracy up to ±0.1 °CSupply voltage range from 1.08V to 3.6VAverage current of 0.4µA (at meas. rate 1Hz)Idle current of 80nAI2C fast mode plus, CRC checksumOperating range from 0 to 100 %RH, -40 to 125 °CFully functional in condensing environmentVariable power heaterNIST traceabilityProduct InformationHumidity Range: 0% to 100% Relative HumidityHumidity Accuracy: ± 1.8% RHTemperature Accuracy: ± 0.2°CRH Response Time: 8sTemperature Response Time: 2sSensor Interface Type: I2CSensor Output Type: DigitalSensor Case Style: DFNNo. of Pins: 4PinsOperating Temperature Min: -40°COperating Temperature Max: 125°CSupply Voltage Min: 1.08VSupply Voltage Max: 3.6VProduct Range: SHT4x Series
