Automatic water level monitoring and seat availability details in train using wireless sensor network

Railway has a valuable role in economic development of each country. The invention concerns a sensor for determining the occupancy of a seat in a railway vehicle and water level monitoring in train. For customer support reasons, it is important to know how many seats, and which specific seats, are available or occupied within a train. This may help the passenger to choose preferred option to travel if they know the availability of seats in the train. The proposed approach not only detects the current seat occupancy of every single seat, it also provides the information in real time. The current status of every seat can be displayed in the PC in monitoring section. The seat availability is checked using array of IR sensors. The water level in the train will be monitored using Float water level sensor. The data is transferred through wireless mesh sensor network through UART(Universal Asynchronous Receiver Transmitter).
