• This full reverse costing study has been conducted to provide insight on technology data,
manufacturing cost and selling price of the Cambridge CMOS Sensors CCS801 Gas Sensor.
• It is a Volatile Organic Compound Gas Sensor manufactured by Cambridge CMOS Sensors for
consumer applications. The Gas Sensor is glued on a DFN package and protected by a cap.
• The CCS801 component integrates a Gas Sensor without IC die.
• The Gas Sensor die comes in a 4 pins DFN package.
• The CCS801 applications:
• Total VOC sensor for Indoor air quality monitoring
• Alcohol breath analyser
• Toxic gas (CO) detection

Reverse costing analysis represents the best cost/price evaluation given the publically available data, and estimates completed by industry experts.
Given the hypothesis presented in this analysis, the major sources of correction would lead to a +/- 10% correction on the manufacturing cost (if all parameters are cumulated).
These results are open for discussion. We can reevaluate this circuit with your information. Please contact us:
