摘要：As the demand for air quality detection increases, there is a pressing need for performance improvement and operational efficiency in gas detection. A high-performance volatile organic compounds (VOCs) monitoring system has been developed, which integrates homemade MEMS sensors with ultraviolet (UV) micro-LEDs, allowing for the modulation of both the operating temperature and light source intensity. Furthermore, the Bluetooth Low Energy module enables wireless communication with mobile phones, allowing for real-time data acquisition under multifunctional conditions. A combination of temperature and UV light co-modulation can significantly enhance sensor response performance while reducing operating temperature (from 300°C to 100 °C) and energy consumption (less than 1/6 of the original). Our work presents novel insights and methodologies for constructing high-performance, low-power VOCs sensing systems. ? 2024 IEEE.
