Sensirion environmental sensors

Sensirion is a designer and manufacturer of flow and environmental sensors, useful for applications including air purification, indoor air quality monitoring and carbon dioxide detection.

The Sensirion SGP40 indoor air quality sensor is an integrated CMOSens sensor system on a single chip that provides a humidity-compensated indoor air quality signal. The sensor offers long-term stability in terms of response time and sensitivity, making it useful for applications including kitchen hoods, thermostats and demand-controlled ventilation.

The SPS30 particulate matter sensor is an optical sensor that combines laser scattering with Sensirion’s contamination-resistant technology. Built for a lifetime of more than eight years, the sensor enables measurements for HVAC equipment, air conditioners and Internet of Things (IoT) devices.

The STC31 is a chip-sized gas concentration sensor, offering high-range CO₂ measurements for high-volume production. The sensor is based on a thermal conductivity measurement principle, which results in good repeatability and long-term stability.

The SFA30 formaldehyde sensor module is based on the company’s electrochemical technology and provides good formaldehyde sensing performance with low cross-sensitivity to other volatile organic compounds. The sensor module is designed for simple integration into air purifiers, indoor air quality monitors and demand-controlled ventilation systems.
