Cambridge CMOS SENSORS – ULTRA-LOW Power Gas Sensors

Industry Leading gas sensors and solutions

Technology Overview
Cambridge CMOS Sensors (CCS) Metal Oxide (MOX) gas sensors are developed using unique technology platforms enabling sensor miniaturization, low power consumption and ultra-fast response times for a wide range of applications.

CCS gas sensor platforms incorporate a proprietary micro hotplate architected into a highly reliable thermally isolating structure. When combined with CCS advanced MOX materials, provide a family of ultra-small MOX gas sensors. To maximize the MOX gas sensitivity the material is heated to a stable elevated temperature. The internal heating element brings the MOX material to temperature (150°C to 450°C) within milliseconds. The sensitivity of the MOX material at these temperatures combined with advanced algorithms give an indication of the gas concentration present.

Benefits of CCS8xx Sensor Product Family
CCS miniature gas sensors use a unique silicon platform with advanced sensing materials, with:
• Highly sensitive and ultra-fast response times
• Reliable and stable gas detection
• Ultra-low power consumption for portable handheld devices

Advanced algorithms support the CCS8xx family of MOX gas sensors for easy and timely integration into a wide range of applications.
