Low-power CMOS gas sensors, in distribution

April 08, 2015 // By Graham Prophet
Cambridge CMOS Sensors’ devices are available from distributor Future Electronics; the devices combine CMOS and MEMS semiconductor technology in a compact, highly integrated package

Future Electronics is to distribute Cambridge CMOS Sensors’ (CCS), the UK-based fabless manufacturer of surface-mount MEMS/CMOS gas sensors, products.This distribution agreement makes CCS’s compact, low-power gas sensors available to a mass market of industrial and consumer electronics OEMs.

CCS provides a growing portfolio of gas sensors measuring carbon monoxide and a wide range of volatile organic compounds (VOCs), used in indoor air-quality monitoring, and ethanol, used in breath analysis. They combine an embedded micro-hotplate and a gas-sensing MEMS membrane in a very compact package. Through the use of advanced MEMS technology, CCS has reduced the time taken to detect target gases compared to other gas sensors on the market today. This enables the application to spend longer in lower power pulse modes reducing the average power consumption.

At 2 x 3mm in a DFN package, a device such as the CCS801 multi-gas sensor is small enough to be embedded into space-constrained devices such as smartphones, and is also suitable for use in many other categories of consumer and industrial products.

CCS’s range of gas sensors are used in applications such as air-quality monitoring and breath analysis. Technical assistance from Future Electronics’ local field applications engineers will also help OEMs’ design engineers to integrate CCS’s analogue gas sensors into system designs. Future Electronics will also sell CCS’s forthcoming digital versions of its devices.

Designers wishing to evaluate the Cambridge CMOS Sensors range of VOC, CO and ethanol sensors may apply for free development boards from the Future Electronics FTM Board Club at www.my-boardclub.com The EVK02 is a full-featured main board with a header for daughter boards for each of the CCS sensors. Boards are supplied free to commercial design engineers, subject to qualification.
