Abstract

Objectives: To develop a portable, low cost and efficient pollution monitoring device. Embedded module can be placed on rooftop and display will show the ambient quality values. Methods/Statistical Analysis: We have adopted the method of data acquisition in real time using semiconductor sensors of MQ series. The sensor data is sampled with help of AVR microcontroller, processed with the program and the values are displayed on LCD. Power consumption is tried to keep low by using sleep mode of microcontroller. The processed data is uploaded on cloud platform and analysed for critical parameters. Findings: The data could be accessed by the user and even government authorities to monitor air quality in real time and take precautionary steps. This low cost & portable solution has semiconductor sensors interfaced with AVR microcontroller. It needs very low power & to make it work independently we can include solar energy to power it. The data taken is validated at different location and with the data of standard equipment setup at locations. Application/ Improvements: Device finds application in industries, educational institutes and public places. Adding more sensors for detection of other gases would improve monitoring of various gases in environment.
