Formaldehyde Sensors & Sensor Modules

Sensirion Formaldehyde Sensors and Sensor Modules deliver accurate, selective HCHO measurement for indoor air quality systems. Formaldehyde sensing distinguishes the harmful gas from other commonly present volatile organic compounds, supporting reliable monitoring in air purifiers, air conditioners, ventilation systems, and standalone air quality instruments. The portfolio incorporates dedicated low-power sensing and multi-parameter environmental modules to meet varied integration requirements.
