Environmental sensors chip in

The Sensirion SGP40 indoor air quality sensor, available from Mouser, 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, providing a reliable solution for applications including kitchen hoods, thermostats and demand-controlled ventilation,” says Mouser.

“Over the past two decades, Sensirion has grown to become one of the world’s leading designers and manufacturers of flow and environmental sensors. These high-performance products are essential for applications that are top of mind in today’s homes and factories, including air purification, indoor air quality monitoring, and carbon dioxide detection.”

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 SPS30 sensor enables accurate measurements for HVAC equipment, air conditioners and Internet of Things (IoT) devices.

“Sensirion’s STC31 is a chip-sized gas concentration sensor, offering accurate, high-range CO2 measurements for high-volume production. The STC31 sensor is based on a thermal conductivity measurement principle, which results in outstanding repeatability and long-term stability,” adds Mouser.

“The SFA30 formaldehyde sensor module is based on Sensirion’s electrochemical technology and provides exceptional formaldehyde-sensing performance with low cross-sensitivity to other volatile organic compounds.”

The SFA30 sensor module is designed for simple integration into air purifiers, indoor air quality monitors, and demand-controlled ventilation systems.
