Summary of ams develops MEMS VOC gas sensor
This article discusses the development of resistive gas sensors, specifically highlighting ams AG's AS-MLV-P2 MEMS sensor for VOC detection. Designed for low power and small size, this sensor utilizes metal oxide semiconductor (MOS) technology to provide accurate pollutant identification. It is currently integrated into Withings' home monitoring systems, offering stable operation with minimal energy consumption.
Parts used in the AS-MLV-P2 MEMS Gas Sensor Project:
- AS-MLV-P2 MEMS gas sensor component
- Metal oxide semiconductor (MOS) technology
- Proprietary MEMS technology
- Surface-mount package
- Low-power integrated analog front ends
- Heating circuitry
- VOC detection system
- Home monitoring system
Gas sensing techniques are continually being investigated to improve selectivity and sensitivity of identifying different types of gases. There are resistive gas sensors, quartz crystal microbalance, direct thermoelectric, electrochemical cell and other exotic types such as MEMS-tunable Fabry-Perot filter spectral sensors with lead-selenide detector and pulsed broadband infrared emitter light source. The ams sensor is a resistive type.
The resistive sensor design relies upon heating circuitry for temperature control of the entire system. There are different types of resistive gas sensor techniques and construction. Some are based upon metal-oxide (MOX) thin films which are small in size, low-cost, and low power as well as able to use low-power integrated analog front ends.
ams AG 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.
The gas sensor
The ams sensor is accurate, small and power efficient which produces a precisely varying resistance as the ambient level of pollutants changes. The sensor’s accurate VOC detection capability results from the implementation of proprietary MEMS and metal oxide semiconductor (MOS) technology developed by ams. The sensor is available in a surface-mount package and in a small footprint and offers long-term stable operation, while only consuming a low amount of power (typically 34mW in continuous operation).
