Humidity sensors
Optimize efficiency and extend system lifetime with humidity sensors
The need for improved reliability and safer, more comfortable environments has increased the adoption of relative humidity (RH) sensors to measure water vapor. Our humidity sensor portfolio offers enhanced reliability, high accuracy and low power to enable more efficient, long-lasting systems.
Why choose our humidity sensor ICs?
Extend system reliability with enhanced sensing
Achieve greater reliability with low drift in long-life industrial and automotive applications. Less than 0.21% RH drift per year and VOC contamination correction.
Increase system efficiency with high accuracy
Our devices are rigorously tested and trimmed for RH and temperature accuracy. Our test setup is traceable to NIST standards and verified by ISO/IEC 17025 policies.
Increase lifetimes for battery-operated systems
Reduce the frequency of battery changes and charging with ultra-low power (nanoampere) consumption across a wide supply range that enables low-power operation while actively running and in sleep mode.

Achieve higher power efficiency and reliable operation across –40°C to 125°C and 0% to 100% relative humidity with our integrated temperature- and humidity-sensing solutions
In appliances, temperature sensors help maintain and monitor both cold (freezers, refrigerators) and hot (ovens, heaters) environments. In appliances that involve moisture (dishwashers, washing machines), humidity sensors help monitor operating conditions to prevent leaking.
Benefits:
- Leak detection to determine whether parts need replacing and to protect battery-management systems from corrosion.
- Relative humidity drift correction lowers long-term sensor drift.
- Removable tape cover and permanent Ingress Protection (IP) 67 filter options for harsh environments.
