IoT Enabled Environmental Monitoring System

Nowadays, global warming poses a serious threat to our planet. For this reason, the reduction of the gas emitted into the atmosphere is increasingly sought for its purpose. Wireless Sensor Network (WSN) to monitor the concentration of carbon dioxide can therefore be helpful in monitoring air quality. In this research, the integration of wireless sensor networks into IoT is implemented for environmental monitoring. Subsequently, a practical case is described consisting in the implementation of a driver for reading the value of the environmental CO2 concentration, through a sensor with NDIR technology. This paper presents a customized design of an IoT enabled environment monitoring system to monitor CO2 concentrations. Moreover, the performance of low-cost Non-Dispersive Infra-Red (NDIR) was assessed. Thereafter, data related to the operation of the sensor will be graphically reported, as well as a sampling window that is executed to perform the measurement. Finally, possible future developments of the driver will be presented.
