Abstract: The paper presents a control system to prevent the explosion of chemical plants by measuring parameters and alert the personnel in case of emergency. The proposed system uses raspberry Pi to collaborate the values of parameters such as temperature, pressure and air quality and checks whether the values crosses the threshold value set. In case, if the values cross the value determined then the alert is given as message. Thus, this method shows that the explosion in chemical plants can be controlled thereby preventing the huge damage to the people and the environment around.
