Featured applications
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.

Achieve system-level protection and reliable operation across –40°C to 125°C and 0% to 100% relative humidity with our integrated temperature- and humidity-sensing solutions
In heating, ventilation and air-conditioning (HVAC) systems, humidity and temperature sensors enable accurate monitoring to keep buildings comfortable and safe, taking corrective action if indoor environment or electrical component humidity and temperature levels are outside an acceptable range.
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.

Optimize camera module performance and increase reliability while streamlining functional safety certification with our integrated temperature- and humidity-sensing solutions
In automotive and industrial camera modules, humidity sensors prevent camera fogging and detect condensation on a lens or complementary metal-oxide sensor that could damage other components, thus helping increase reliability.
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.
- Automotive-qualified and TI Functional Safety-Capable.
