Automatic Breaks in Hill Station by Ratchet and Pawl Mechanism

The main aim of the project is to design and construction of a module used for vehicles in the hill stations. Auto breaking system is used when vehicle is climbing on hill station. The project was divided into two phases. The First phase is to demonstrate the application of MEMS. The second phase of the project attempts controlling motors. MEMS sensor is interfaced to micro controller using I2c protocol, microcontroller receives the data from the MEMS sensor and process it according to the data from the sensor appliances are operated. Application are like refrigerators, microwave ovens, Theaters hospitals etc. I2C protocol is used for interfacing MEMS sensors with micro controller, Micro controller main functionality is to receive signals for sensors and process information by taking desired decision. MEMS-based sensors are a class of devices that builds very small electrical and mechanical components on a single chip. MEMS-based sensors are a crucial component in automotive electronics, medical equipment, smart portable electronics such as cell phones, PDAs, and hard disk drives, computer peripherals, and wireless devices. These sensors began in the automotive industry especially for crash detection in airbag systems. Throughout the 1990s to today, the airbag sensor market has proved to be a huge success using MEMS technology. MEMS-based sensors are now becoming pervasive in everything from inkjet cartridges to cell phones. Every major market has now embraced the technology.
