Implementation of a System for the Evaluation of Environmental Factors that Use the Internet of Things

Abstract

Environmental factors influence the deterioration of human health, causing various diseases and depend on prolonged exposure in environmental environments where these factors are found in extremely harmful indexes for people. In recent years, the most worrisome environmental factors are air pollution due to the different concentrations of polluting gases and the high rates of ultraviolet radiation. If the time of exposure to the factors is greater, then the damage to health will be harmful. It is estimated that 24% of annual deaths worldwide and 33% of diseases in children under 5 years of age are due to exposure to risks due to environmental factors that could be prevented. For this reason, a measurement system was implemented to evaluate environmental factors and prevent existing diseases. The research project uses the NodeMCU ESP8266 platform for the development of the Internet of Things (IoT), which will allow sending the data to the server using the internet technology of things, where the data acquired by measuring the electrochemical sensors (MQ), temperature and humidity (DHT-22) and ultraviolet radiation sensor (GYML8515). This system works using a Blynk server allowing to monitor the data in real time.
