Gassensor holder øje med køkken-miljøet

ams har lanceret en MEMS-baseret iAQ-Core K sensor-modul, der tilbyder en pålidelig detektion af uønskede dampe, lugte og røg, der opstår i forbindelse med madlavning (in english).

ams has released a new version of its iAQ-Core module, a low-power gas sensor for the detection of steam, odors and fumes in kitchen applications. The iAQ-Core K is the latest member of the ams iAQ-Core family of advanced MEMS gas sensing modules, and is supplied in the same small (18mm x 15mm), robust package. It is resistant to air-borne contamination by water vapor, dirt or grease, and operates reliably when exposed to the high concentrations of volatile organic compounds (VOCs) and humidity often found in kitchens.


This latest module in the iAQ-Core family combining the existing features of previous modules along with a new algorithm for detecting steam, cooking fumes and kitchen odors. The iAQ-Core K provides measurements of the relative concentration of VOCs and steam to a host controller, and the architecture enables automatic control of fan speed in cooker hoods or in a kitchens demand-controlled ventilation system.

In either application, the sensor reliably detects rapid changes in humidity and gas composition that are characteristic of cooking processes. The fast response of the modules new algorithm means cooker hoods or demand-controlled ventilation systems can automatically maintain consistently good indoor air quality in the kitchen, while helping conserve energy by activating ventilation fans only when needed.

Compact, robust MEMS technology is enabling the integration of gas-sensing technology into
many end product types for the first time, says Stefan Crijns, Head of business line environmental sensors at ams.

- With the release of the iAQ-Core K module, manufacturers of cooker hoods can now easily integrate a reliable gas-sensing device into their products with minimal development effort, and substantially increase the value of their products to the consumer by enabling automatic operation. This means, for instance, that the cooker hood can automatically detect humidity or odors and increase or decrease the fan speed when the user is occupied with tasks away from the stove top.
 
The iAQ-Core modules K variant is available in December 2018.
