Withings Room Monitor Helps Keep Air Quality High Indoors Thanks to MEMS VOC Gas Sensor from ams

Business Wire
ams AG (SIX: AMS), a leading provider of high performance
sensors and analog ICs, today announced that it is supplying its
AS-MLV-P2 MEMS gas sensor component for VOC (volatile organic
compound) detection to Withings for use in its innovative new Home
monitoring system.
Accurate, small and power-efficient, the AS-MLV-P2 sensor
produces a precisely varying resistance in response to changes in
ambient levels of pollutants commonly found in indoor
environments.
The size, accuracy, reliability and low power consumption of the
AS-MLV-P2 make it perfect for air quality monitoring applications
in smart home and IoT devices. In Withings’ stylish and compact
Home product, the AS-MLV-P2 is combined with a 5Mpixel video
camera, dual microphones, temperature and humidity sensors and
Wi-Fi® and Bluetooth® Smart radios. This means that users of the
Home monitoring system can see, hear, feel and smell the inside of
their home remotely via a smartphone or tablet app supplied by
Withings.
The AS-MLV-P2 measures ambient concentrations of a broad range
of reducing gases associated with bad air quality such as alcohols,
aldehydes, ketones, organic acids, amines, and aliphatic and
aromatic hydrocarbons, which can be harmful to human and animal
health at high levels. In the Home app, the sensor’s measurements
of these chemicals are converted to an air-quality rating as well
as to a measurement of VOC concentrations.
The Home unit also sends notifications to the user’s phone or
tablet when the concentration of VOCs exceeds pre-set thresholds,
allowing the user to take an appropriate action such as opening a
window, turning on an air cleaner or increasing the fan speed of a
ventilation system.
The AS-MLV-P2 sensor’s accurate VOC detection capability results
from the implementation of proprietary MEMS and metal oxide
semiconductor (MOS) technology developed by ams. This technology
enables devices such as the Home monitor to provide credible data
to consumers concerned about the quality of the air that they and
their families breathe.
ams’s proven AS-MLV-P2 provides a direct measurement of the
concentration of pollutants, giving the user helpful information on
which they can act to protect and improve air quality. Available in
a surface-mount package, it provides this capability in a small
footprint and offers long-term stable operation, while only
consuming a low amount of power (typically 34mW in continuous
operation).
‘A key function of the Home room monitor is to give the user a
simple and credible measure of air quality. We felt that the
integrity of Home’s air-quality rating depended on very accurate
measurements of the key pollutants: VOCs. This is why we chose to
use the AS-MLV-P2 in Home,’ said Cédric Hutchings, CEO of
Withings.
‘Not only is the sensor an excellent product, however, but also
the hardware and software design expertise and support of the ams
engineering team was outstanding, and this enabled us to integrate
the AS-MLV-P2 into our product design with very little
difficulty.’
The gas sensor AS-MLV-P2 is available now in production volumes.
It is priced at $14.30 each in order quantities of 1,000.
