Abstract


Low-cost particulate matter (LC-PM) sensors have been studied around the world as a viable alternative to expensive reference stations for monitoring air quality. However, LC-PM sensors data are often inaccurate and subject to uncertainty, suffering with the conditions of the environment in which they work. This work evaluates the impact of temperature and humidity on 5 LC-PM sensors over a period of 4 months. The LC-PM sensors are compared with a reference equipment in order to propose a methodology to select the MP-BC sensor that will compose a low-cost air quality station in the context of smart cities. Results demonstrate that the evaluated sensors present better correlation with the reference equipment when the readings in which temperature and humidity are critical are taken from the sample.
