Compact and Highly Sensitive NO<sub>2</sub> Photoacoustic Sensor for Environmental Monitoring
A nitrogen dioxide (NO<sub>2</sub>) photoacoustic sensor for environmental monitoring was developed using a low-cost high-power laser diode emitting at 450 nm. A compact low-noise photoacoustic detection module was designed to reduce the sensor size and to suppress noise. A LabVIEW-based...
