For the first idea this project is about the development of automated monitoring device for environmental air pollutant detection. The main part of the device will consists of a detector, microcontroller and timer circuit. The gas sensor will be used to detect air contaminant level, in which the detection through the sensor measures in unit of part per million (ppm). A PIC Microcontroller will be utilized to convert the analogue signal from the sensor into digital signal which finally displays the result through the liquid crystal display (LCD)
