The fire accident is mostly an incipient fault. If this is not treated in early days, it leads to a huge disaster. The combined operation of an extinguishing system and communication system by using IOT is used in this project. Several units are installed in each compartment. Each unit consists of a Humidity sensor, a smoke sensor and a Node MCU ESP 8266 microcontroller. Humidity sensor detects the change in moisture content due the fire while Smoke sensor detects the smoke generated by the fire. When either of the sensor gives output as high, a signal will be transmitted to the microcontroller .The possible way to extinguish fire is using fire extinguisher (fire extinguishing ball) and water sprinkler system. Fire extinguisher ball will be placed in a safety box which is locked with the help of solenoid lock. This solenoid lock gets signal from the microcontroller during emergency condition. So as a result lock gets opened and fire extinguishing ball will fall down from the safety box. When this fire extinguishing ball gets in contact with the fire it extinguishes the fire. If the fire is not quenched, microcontroller activates the water sprinkler system and water is sprayed in the compartment to quench it. The water is drawn from the overhead Aluminium tank which is present in the compartment. Once the fire is detected microcontroller also sends message to the loco-pilot of the train and nearby fire engine using the microcontroller shows the compartment under fire in all other compartments so the people may escape the fire easily. So that the firefighters can reach the emergency spot quick and can take necessary action to extinguish fire.

I. INTRODUCTION The fire incidences in trains are among the most serious disasters to human lives and the property of Indian Railways. Thus the prevention of train fire has become a serious concern for Railways. A train fire is different from a fire in other places in the manner in which it breaks out, grows and spreads, and in the method of fighting it. Fire in a coach on running train is very dangerous because it spreads very quickly to other coaches due to fanning effect.. Disaster can be defined as a horrific event which causes the loss, decline, deterioration of production and loss of human life. Disasters cause huge financial loss and human suffering and death. Disasters can occur as a consequence of the impact of a natural or a human-caused hazard. Natural hazards comprises of earthquakes, volcanic activity, landslides, tsunamis and tropical cyclones. Artificial disasters include illegal discharge of oil, or accidental such as toxic spills and nuclear meltdown. From the reference survey, economic aftermaths have an increasing trend as average annual damages resulting from natural. When train accident occurs in the trains, there had been only few options to extinguish fire and save the lives. Method 1: Use Fire Extinguisher Using fire extinguisher present in the compartment to put off the fire. Fire extinguishers are kept in each compartments Method 2: Alert Fire Fighters Alerting fire fighters to quench the fire. It is also noted that the arrival of fire fighters takes time, depending on the traffic, availability of personnel and equipment etc. There is also possibility of huge property loss and loss of lives. II. DESCRIPTION To forestall the fire accident in train and to communicate about the status of the train to the respective foreperson and the passengers to avoid loss of life. To do this we use two sensors Gas ,Temperature and Humidity sensors when fire occurs it detects it and sends signal to microcontroller the micro controller initiates the buzzer and sprinkler system and sends notification to fire department via Node MCU ESP8266 Wifi module interfaced with IFTTT(IF This Then That )Application through Internet Of Things(IOT). The objectives of the proposed solution could be divided into three general categories. • To Detect any Fire accident in Train. • To Minimise the loss of lives in Fire accident in train.
