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 3.6V Product Overview SHT40-AD1B-R2 is a digital sensor platform for measuring relative humidity and temperature at different accuracy classes. The I2C interface provides several preconfigured I2C addresses and maintains an ultra-low power budget. The power-trimmed internal heater can be used at three heating levels thus enabling sensor operation in demanding environments. The four-pin dual-flat-no-leads package is suitable for surface mount technology (SMT) processing. Relative humidity accuracy up to ±1.5 %RH Temperature accuracy up to ±0.1 °C Supply voltage range from 1.08V to 3.6V Average current of 0.4µA (at meas. rate 1Hz) Idle current of 80nA I2C fast mode plus, CRC checksum Operating range from 0 to 100 %RH, -40 to 125 °C Fully functional in condensing environment Variable power heater NIST traceability Product Information Humidity Range: 0% to 100% Relative Humidity Humidity Accuracy: ± 1.8% RH Temperature Accuracy: ± 0.2°C RH Response Time: 8s Temperature Response Time: 2s Sensor Interface Type: I2C Sensor Output Type: Digital Sensor Case Style: DFN No. of Pins: 4Pins Operating Temperature Min: -40°C Operating Temperature Max: 125°C Supply Voltage Min: 1.08V Supply Voltage Max: 3.6V Product Range: SHT4x Series
