Sensiron introduces the SGP41 VOC+NOx sensor, for indoor air quality applications. The sensor is designed as a digital smart switch and regulation unit for air treatment devices such as air purifiers.
Specifically, the device focuses on VOCs commonly found in building materials, furniture and cleaning products, as well as NOx (nitrogen oxides) which are a by-product of combustion (gas stoves, wood burners, etc.).
Both sensors are located on a single chip, facilitating design-in and cutting design costs, according to the company. In addition, Sensiron’s MOXSens Technology, keeps the sensor robust against contaminants that would otherwise destabilize the sensor’s sensitivity and accuracy over time.
According to Sensiron, the SGP41 is capable of transforming air purifiers, fume hoods, air exchange units and ventilation controllers into proactive air treatment devices by monitoring VOCs and NOx and removing them automatically when the appropriate filters are installed. The two sensor signals can be used to automatically trigger the removal of indoor pollutants without the need for user-device interaction.
