Car drivers often experience difficulties to park their cars in the narrow
location, because the parking area is narrower. Not a few drivers hit the power
pole or deface the walls when parking the car.
This tools system uses a AT89S51 microcontroller
as a main control. Used as input SRF04 ultrasonic sensor module which, it
consists TX (transmitter) and RX (receiver). Output use an LCD (Liquid Crystal
Display) to display the distance and uses speakers for sound indicators.
Results obtained from that car parking sensor prototype based on
AT89S51 microcontroller is a tool can be used to measure the distance of parking.
AT89S51 microcontroller functions is the main data processing equipment on the
resulting distance from ultrasonic sensor. Use module SRF04 ultrasonic sensor,
the car parking sensor prototype based on AT89S51 microcontroller can produce
a more accurate data. Parking distance is presented via LCD display with a
measuring meter. Speaker can be used as sound indicators on the car parking
sensor.
