Abstract: With the increase in the number of industries in the world today, it is important to keep the our environment healthy and no toxic for living creatures. This project concentrates on designing a pollution monitoring system for industries that would be detecting the toxic gases concentration in the atmosphere that is given out by chemical, paper, ammonia, etc producing industries. The system is designed to continuous monitor theconcentration of gases such as LPG, CO, Sulphur, chlorine etc. and warns if increasing level of toxic level of gases are detected. The values of the concentration of gases are logged into the excel file for future reference and perform analysis to understand the pattern of ejecting gases. This project uses Gas sensors and Arduino for detection and transmission of the data to Lab-VIEWsoftware for further process. Index Terms: Lab view, Gas sensors, monitoring, analysis,safety device
