Sensors enable thermostats to operate with accuracy, reliability, and low power consumption

High accuracy at minimal size

Our humidity and temperature sensors deliver unparalleled accuracy and reliability throughout their lifespan, backed by rigorous traceability throughout the production process. Optimized size, packaging, and customizable options seamlessly integrate into your device designs.

Flexibility for any device due to low power consumption

Trimmed to optimize energy consumption, our temperature sensors allow for integration in battery driven as well as wired devices maximizing sensor performance and communication frequency. The power supply is designed to fit even the most demanding designs allowing supply power down to 1.08V.

Ease of integration and design-in

Our temperature sensors report an accurate temperature value to the internal I2C bus. Integration of up to three sensors in the same I2C line offers design flexibility and ease of integration. I2C clocking frequencies supported go up to fast mode plus (1 Mbit/s).

Sensirion cost-effectively packs high-precision sensor technology into a small space. This allows us to design devices with multiple sensors for more accurate, faster, and smarter feedback. Gamal Mustapha Product Manager at Delta Controls

Humidity and temperature sensor STH4x

Our SHT4x humidity and temperature sensors offer an excellent price-performance ratio. The series is characterized by the ideal combination of high accuracy and low power consumption. Thanks to the wide supply voltage range, it is ideal for battery-powered devices and complies with the RESET® and WELL Building Standard™.

The future of improving indoor air quality.

When we think of air quality, we tend to think of air pollution in the regions surrounding our homes. We rely on measures such as the Air Quality Index to let us know when airborne pollutants in our towns or cities reach levels that may cause or exacerbate health issues.
