Low-Cost Sensors for Air Quality Monitoring in Developing Countries – A Critical View
Air quality monitoring in developing countries is in a dismal state. The monitoring of ambient air can be done by conventional/fixed stations and recently emerging low-cost sensors. The study first discusses the low-cost sensor and its differences with respect to conventional sensor. The existing network employing low-cost sensors have been explained in detail to create a better understanding. While deploying these sensors in developing countries one can open a plethora of opportunities; it also poses a number of challenges required to be dealt with, for effective monitoring of air quality
