Wireless Data Acquisition for School Bus

Thousand of children need to travel from home to school and vice versa every day. For parents, obtaining a safe transport for their children is a critical issue. Crime against children is increasing and every parent is requesting the respective school for the security of their child while traveling from school to home and vice versa in school bus .The system will notify parents by SMS whenever children enters or leaves school bus, this will assure parents that children are safely reached to destination . The proposed system shows that, when school bus comes under the college area the whole stored data is transmitted wirelessly to receiver side. Here we use RF module for communication. All the data which is stored at bus unit is transferred to school unit by using RF module. Count through RFID reader will ensure that is school bus is vacant or still any children are inside the school. The RFID reader are interfaced with Microcontroller. Each RFID tag has an information about individual children which was sensed by an RFID reader transmit the corresponding information to their parents using GSM. Speed of the bus also can be calculated. The system consists of three main units, bus unit, parent unit and school unit. The bus unit is used to detect when a child enters/exits from the bus using RFID Card. This information is communicated to the parent unit and school unit that identify the presence of children.
