Gas sensors help wristband measure indoor air quality

Chinese wearable device manufacturer HiCling is using ultra-low power gas sensors to enable its new Cling VOC smart fitness wristband measure indoor air quality and alcohol in breath.
The sensor technology comes from Cambridge CMOS Sensors, a subsidiary of Austria Microsystems (AMS).
The CCS801 gas sensor integrated in the Cling VOC wristband can detect low levels of VOCs (volatile organic compounds) typically found indoors. In the wristband, these VOC measurements are used to provide an indication of air quality on the band’s display.
The wristband can also provide alcohol breath analysis on demand, as the integrated CCS803 gas sensor with algorithms is sensitive to ethanol on human breath.
The small footprint and low profile of the sensors mean they can easily be accommodated in the slim and sleek enclosure of the Cling VOC, which is intended to appeal to fashion-conscious consumers.
“We are delighted that our sensors have been included in the innovative Cling VOC smart fitness wristband,” said Paul Wilson, senior product marketing manager at AMS. “CO2 levels, offensive odours, smoke and other VOCs can have a strong impact on people’s comfort, productivity, quality of life and wellbeing, so it is vital we are able to measure these VOCs. The market demand for wearables is growing strongly with the introduction of attractive products such as the Cling VOC, and we are pleased to be partnering with HiCling and enabling it to differentiate its product in a crowded market place.”
The sensors use a CMOS-based micro-hotplate platform, which enables the device miniaturisation, low power consumption and fast response times that are critical for wearable devices. Software libraries containing proprietary algorithms and example applications for the Android operating environment let the sensors be integrated into a wide range of portable consumer applications.
“AMS group company CCS has developed the world’s smallest and lowest-power MOx gas sensors on the market,” said Richard Chen, CEO of HiCling. “That’s why we are delighted to partner with CCS to provide users with compelling new features in our latest smart fitness wristband. Most people spend most of their time indoors, so it is important that they are able to monitor air quality easily and to take appropriate action, something wearers of the Cling VOC wristband can now do.”
The gas sensors are available in production volumes now. The wristband will be available to buy online from Amazon, Tmall and JD.
