Tiny, low-power AS-MLV-P2 MEMS gas sensor helps Eve Room run for
months on a small, replaceable battery
ams AG (SIX: AMS), a leading provider of high performance sensors and
analog ICs, today announced that Elgato (www.elgato.com)
is using the ams AS-MLV-P2 MEMS VOC (volatile organic compound) gas
sensor in its new Eve family of home monitoring devices.
The 9.1mm x 9.1mm x 4.5mm AS-MLV-P2 is a low-power gas sensor which
measures levels of VOCs in the ambient air with unrivaled accuracy. It
produces a precisely varying resistance in response to changes in
ambient levels of pollutants commonly found in indoor environments.
In Elgato’s Eve Room, the measurements of VOC concentrations captured by
the AS-MLV-P2 are converted into an indoor air-quality score. Eve Room
also gives the user temperature and humidity readings.
Its design is sleek, unobtrusive and easy to configure and use. Highly
power-efficient, it has no wired connections, using a low-power
Bluetooth® Smart radio for communications and a replaceable battery for
power. The low-power operation of the AS-MLV-P2 was therefore
particularly attractive to the Elgato design engineering team.
Traditionally, gas sensors have been power-hungry devices, drawing a
high current to supply their heated sensing element. The revolutionary
micromachined design in the AS-MLV-P2 developed by ams achieves very
high sensitivity to low concentrations of VOCs while consuming just 34mW
in normal operation, making it ideal for battery-powered products such
as Eve Room. The highly repeatable production process used to fabricate
the surface-mount gas sensor also results in extremely stable operation
over the lifetime of the end product.
The AS-MLV-P2 directly 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. These VOC measurements provide a more useful measure of indoor
air quality than the carbon dioxide sensors commonly used for air
quality monitoring today, since CO2 concentrations are
strongly affected by the presence of human beings and animals, which
exhale the gas.
In Eve Room, the AS-MLV-P2’s VOC measurements are displayed in the free
Eve app, which runs on any compatible iPhone, iPad or iPod Touch device.
Displaying attractive graphs and comparison charts, the app provides
insights that help users to make their home environment healthier and
more comfortable, while benefiting from the latest smart home automation
technology.
‘Thanks to the VOC sensor from ams, Eve Room measures indoor pollution
levels with great accuracy at the same time as featuring a user friendly
and battery-powered design,‘ said Dr. Markus Fest, CEO of Elgato. ‘The
technology and support provided by ams enabled Elgato to deliver one of
the most advanced products built for Apple's HomeKit platform.’
The AS-MLV-P2 gas sensor is available now in production volumes. Unit
pricing is $14.30 in order quantities of 1,000.
