SENSIRION Temperature and Humidity Sensor- SHT45-AD1B-R2, 0% to 100% RH, -40°C to 125°C, I2C, Digital, DFN-4, 1.08 V to 3.6 V

Digital humidity and temperature sensor with ultra-high accuracy of ±1.0% RH and ±0.1°C. Building on Sensirion’s 20 years long humidity and temperature sensors experience, the SHT45 offers the best accuracy tolerances on the market. Additionally, tape and reel packaging combined with its suitability for standard SMD assembly processes make the SHT45 ideal for high-volume applications. The SHT45 builds on a new and optimized CMOSens® chip offering ultra-low power consumption and industry-leading accuracy specifications. The SHT45 covers operating ranges from 0 to 100% RH and from -40°C to 125°C with accuracies of ± 1.0% RH and ΔT = ± 0.1°C, ensuring reliable measurement results thanks to its long-term stability and high precision. The exceptionally small size in a robust DFN housing enables integration into challenging designs while meeting the highest reliability demands, as demonstrated by the JEDEC JESD47 qualification.
