Abstract
A compact and easy to use photoacoustic (PA) detector has been developed for the detection of nitrogen dioxide (NO2). The detector is based on an integrating sphere as the PA absorption cell and LEDs as light sources. Combined with low-cost microphone the PA sensors provide a highly sensitive and low-cost solution for NO2 monitoring. The PA sensor can easily be modified to measure many different atmospheric trace gasses simply by changing the wavelength of the light source.
