LED-based gas sensors: A review

In many applications, light emitting diode (LED) based gas sensors are becoming more and more significant. Absorption, transmission, and fluorescence spectroscopy LED-based sensing methods provide outstanding stability, selectivity, and sensitivity for the wide range of applications anticipated for sensors built into mobile and wearable technology. Furthermore, the activation of metal oxide semiconductors with UV-LEDs improves the efficiency of semiconductor gas sensors. Some of the current developments in the integration and shrinking of optical gas sensors with an emphasis on low-cost and low-power gadgets are discussed.
