  • Abstract
    This work reports a real-time, non-invasive, compact and field deployable CO2 sensor using tunable diode laser spectroscopy (TDLAS). Direct detection and 2f-WMS was used to measure the gas parameters utilizing a low power vertical cavity surface emitting laser (VCSEL) emitting across 2003.5nm where CO2 has a strong absorption line. A Raspberry Pi microcontroller along with a serial analog-to-digital (ADC) convertor was used for data acquisition and processing to make the system compact and field deployable.
