cambridge flyerFirst gas sensor with ultra low power consumption developed for the portable handheld devices

New entrant in the Gas Sensor market, Cambridge CMOS Sensors is focused on the future mobile market with ultra low power consumption products.
The objective is the integration of gas sensor in smartphones in order to offer new functions like pollution monitoring, alcohol breathalyzer and toxic gas (CO) detection.

The CCS801 is a volatile organic compound gas sensor which can detect Carbon Monoxide (CO), a wide range of Volatile Organic Compounds (VOC) and which can also be used as a CO2 equivalent sensor.

With a very small footprint, only 6mm², the package is adapted to consumer applications. The sensor die area is very tiny. No ASIC has been integrated in the package.
The die is based on a Metal Oxide sensitive layer made on a micro hotplate. This allows a very low power consumption: 1.6mW for one measurement. Moreover, the die is using some of the last technologies developed for the MEMS microphones.

Cambridge CMOS Sensors is a young company and the CCS801 is their first product for large volume. CCMOSS has developed a complex SiO2 membrane and a multi-heater to reduce the duration of the measurement.

The report provides all details on the structure of the component and the supply chain to produce this MEMS sensor. The report includes a detailed technology and cost analysis describing the innovations of CCMOSS and a comparison with the AS-MLV-P2 from AMS-Applied sensor.

Gas Sensors Cost Comparison



Across the Enterprise, from marketing to purchasing and R&D, product manufacturing cost is a major factor which has to be measured and then optimized. Since 1993, System Plus Consulting’s mission has been to develop and sell the right tools and services to meet these costing requirements.

System Plus Consulting utilizes an engineering approach to cost. Cost models and technology expertise are combined to provide customers with an accurate and objective estimation of manufacturing costs and selling prices.

Headquartered in Nantes, France, System Plus Consulting is specialized in technology and cost analysis of electronic components and systems. During our 20 years in business, we have built and refined detailed cost models as the primary tools for hundreds of analyses. The highly qualified System Plus cost engineers combine broad and deep skills in semiconductor and electronics technologies with years of experience in cost modeling.

We offer:
− Custom reverse costing analyses: technology analysis followed by cost evaluation
− Standard reverse costing reports: regular publications on innovative products (available from our catalogue)
− Costing tools: software tools combining models and data to perform cost analysis

System Plus Consulting analyzes any type of electronic devices and systems, with a special focus on semiconductor technologies. Major fields of technology and cost expertise are:
− Integrated Circuits
− Power Devices and Modules
− MEMS & Sensors
− Photonics: LED, Image Sensors
− Packaging including wafer level
− Electronic Boards and Systems

Our analyses are used by Purchasing Departments to measure their suppliers’ cost structure, R&D Departments to confirm technological choices depending on their impact on costs, and Benchmarking/Marketing Departments to monitor the products on the market.

System Plus Consulting is committed to provide a high level of service:
− Delivery of reports and custom analyses with a minimum lead time.
− Results presentation and online Q&A sessions when support is needed.
− Open methodology and full confidentiality in order to maintain a trustful collaboration.

Since 2008, our partnership with YOLE Développement has allowed us to stay at the forefront of technologies and has added a market view to our reports.
