Abstract :
Infrared sensor system consists of an infrared LED and photo diode. Photo diode is an infrared light detector which assisted the transistor amplifier. In this scheme is used to detect the speed and length of objects. The process of detecting speed and length of an object started when an object passed through the infrared sensor. Photo diodes will transform the incoming light into a voltage, the amount of voltage going into the series and will get the logic output as input to the microcontroller. Data is entered into the microcontroller will be processed by the program that have made using CodeVision ATMega. Using the formula in physics is the distance divided by time, the result will appear on 2x16 LCD screen The measurements of speed are calibrated using a stopwatch as a timer, the speed of the object will be obtained by using the formula of speed, with the assumption of a designated distance. The length of objects are calibrated using a ruler. Measurement errors at speeds up to 3.36%, the length measurement error reaches 2.59%. Overall, The design of speed measuring device using infra red sensor is running good enough.
