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
