Automatic toll payment, alcohol detection, load and vehicle information using Internet of things & mailing system

Present days, the technology has emerged in such a way that it can provide solutions to any real life problems. One such solution to the problem of collecting toll payments efficiently is RFID. When a vehicle passes through the toll gate, by using RFID the vehicle can be detected easily and the amount will be deducted from the user's prepaid account automatically. In order to detect the drunken drivers, Alcohol sensor (MQ135) is fixed near the driver steering. If the alcohol consumed by the driver exceeds the limit detected by sensors automatically accelerometer reduces the speed. The load detector fixed at the toll gates checks the load of heavy vehicles if load exceeds the limit, the barrier remains closed and the camera captures a snap of the vehicle. And also the notification will be sent to the consignment officer for registering complaint against the vehicle and also penalty amount will be deducted from the owner's account.
