Renesas offers innovative, high-performance environmental sensors for indoor air quality (IAQ), outdoor air quality (OAQ), refrigeration air quality (RAQ), industrial leak detection and humidity detection. Renesas' gas sensors are capable of accurate detection of Volatile Organic Compounds (VOCs), nitrogen oxides (NOx), ozone (O3), hydrogen (H2), and other flammable gases, and leverage advanced sensing materials with more than 15 years of proven stability and reliability.

Renesas provides the following environmental sensor platforms to fit your needs: analog and digital gas sensors, thermopile CO2 detectors and humidity sensors. The digital ZMOD gas sensor platform is an integrated digital and calibrated gas sensor ideal for high volume consumer and industrial air quality applications, while the analog SGAS gas sensor family is best suited for industrial control and leak detection applications. The thermopile CO2 detectors support CO2 sensors requiring high precision and performance. The humidity sensors offer high accuracy, fast measurement response times and long-term stability enabling customers to improve overall system performance and feedback control.
