Contactless Tachometer and Wireless Telemetry

In this kit contactless tachometer and wireless telemetry we are monitoring the speed of any wheel wirelessly using X Bee modules. The speed is displayed at both ends on the LCD. IR sensors are used to sense the speed of the wheel. There is a cut at the edge of the wheel from where the IR can pass. Using this arrangement the speed is measured by the microcontroller and also it is transmitted at the other end using X Bee modules. The data from IR transmitters is in analog form.
