"IHS expects that Chinese smartphone makers will be the early adopters of air quality sensors. During its interviews with smartphone OEMs, Chinese OEMs showed the most interest in air quality sensors," said Jeremy Bouchaud, Director and Senior Principal Analyst for MEMS & Sensors at IHS. "Chinese smartphone OEMs are becoming more daring than their Western or Korean competitors when it comes to adopting new MEMS technology. The recent adoption of RF MEMS antenna tuners (from Cavendish Kinetics) by ZTE is a good example."
IHS does not believe that the previous generation environmental sensor from Bosch (humidity, pressure, and temperature) introduced at last year's CES has had much traction yet. But in its recent forecast “Emerging sensors for handsets and tablets” IHS believes that Bosch will get some traction with a new combo sensor which includes an air quality sensor in 2015 in China.

"Bosch already introduced a year ago a pressure, humidity, and temperature sensor," Bouchaud told us. "Adding indoor air quality sensor is the obvious next step and Bosch will be the first one to introduce such a package."
Bouchaud said he expects other suppliers to introduce discrete gas sensors in handsets later in 2015. For instance Bouchaud said IHS believes that Cambridge CMOS Sensors (CCMOS, Mass.) has been designing gas sensors in some handsets which will hit the market in 2015.
Still a ways to go
Bouchaud points out, however, that while the gas sensors built into new MEMS chips to be introduced at CES will be appealing to the Chinese market, in particular, unfortunately they do not directly address the most prevalent type of pollution there -- fine particulate from smokestacks and the like.
"The issue of air quality in large cities in China makes an air-quality sensor feature more appealing there," said Bouchaud. "One must note however that the gas sensor technologies introduced at CES will not be able to measure fine particulate in air. IHS does not believe that a sensor technology for measuring fine particulate will be available for handsets in the next 3 years."
