Humidity sensor ICs

Accurately measure relative humidity and temperature with industry leading ultra-low power and small-size humidity sensors

High accuracy

High accuracy

Our humidity sensors accurately measure relative humidity and temperature in a single integrated circuit. The combination of sensors makes it ideal for control loops, robust HVAC feedback, and controlling environmental conditions for comfort.

  • Relative humidity accuracy: 2%
  • Temperature accuracy: 0.2°C
Small size

Small size

The available package options enable compact designs, and fast temperature and humidity response times. Our humidity sensors are offered in two small size package options that empower robust designs while saving space.

  • WCSP:1.46mm x 1.46mm x 0.24mm
  • QFN: 3mm x 3mm x 0.8mm
Ultra-low power humidity sensors

Ultra-low power

Managing the power consumption of humidity sensors used in battery operated devices is made easy with programmable auto measurement mode. Reducing current consumption during measurements saves power for more intensive components in a system.

  • 1 measurement/second: 0.55µA
  • 1 measurement/2 seconds: 0.3µA
  • Sleep mode: 0.05µA

Key industrial applications

  • Thermostats - HVAC systems are becoming increasingly more complex. The addition of humidity sensors to these systems allow for offices and homes to measure and adjust for a comfortable amount of humidity in the air.


  • IP network cameras - Wireless network security cameras can be placed in locations that may cause condensation formation on lenses or environmental covers. With the combination of a humidity and temperature sensor on a single IC, we have a solution that will predict the point at which condensation will occur.


  • Cellular module asset tracker - When developing cold chain networks, it is important to understand the enviroment(s) goods will enter before, during, and after transit. Monitoring the humidity and temperature validates the environmental quality of perishable goods as they are transported to their final destinations.
