Bomb Detector for Railways

Automatic detection of explosives using wireless sensor networks monitors and tracks the IEDs that are placed by terrorists at public environments. The area under study is monitored in real time, collect data by the sensor and send to the processor which process the data and compares with the database and if there is a match the processor enables the buzzer which provides early warning to the people in that area. Current system in operation uses sensors which are very expensive and not very sensitive and also uses a good deal of power. The paper sensor is coated with chemical compounds that are frequently used in explosives so that it will be easy for the sensor to know the type of IED used.
