IoT Firmware on Micropyhton Framework with Environmental Sensors and Network Functionalities

Abstract

The air pollution is increasing along with the growth of cities and industries everyday. The quality of the air needs to be known and thus, to be measured. The device measures the environmental parameters such as Temperature, Humidity, Pressure, Light, Dust Particulate Matters, Carbon Dioxide and Carbon Monoxide using accurate, sustainable and reliable digital sensors. This device is designed to work in constrained embedded system which is achieved by integrating the sensors with low power micro-controller. Firmware of this device is built on the lightweight MicroPython framework. The device runs faster with the compact hardware and less internal memory usage. Moreover, Long Range(LoRa) technology is integrated to enable communication with low power and wider range between remote sensors and gateway connected to the network. The sensor data is sent to network server and is observed using various graphical representations on the web application.
