Ultrasonic Distance Measurement HC-SR04 Ultrasonic Sensor Based On 8051 Microcontroller
If
u want to measuring a distance usually we are using measuring tape or another
tools but this kind of tools having limitations and manuals error and there are
many industry where we need to measure a particular distance from object. There
areseveral ways to measure distance without human contact like infrared ray,
radar, laser but they are very expensive, hence the ultrasound waves can be
used for applications in industries/vehicles without hindering human activity.
So
here we introduce Ultrasonic distance measuring system which measures the
distance of any object by using an ultrasonic module comprising of a
transmitter and receiver interfaced to a microcontroller.
To get distance of object from current position

In
the system we used ultrasonic sensors to measure sensors by using pulse echo and
phase measurement method and an
ultrasonic module is interfaced to the microcontroller, and an ultrasonic
transducer comprising of a transmitter and receiver and it will transmitted the waves.
If any
object is comes under the range that we are set to the transducer then the
transmitted waves are reflected back from the object and received by the
transducer. The total time taken from sending the waves to the receiving end is
calculated by taking into consideration the velocity of the sound. Then, the
distance is calculated by a program running on the microcontroller and
displayed on an LCD screen interfaced to the microcontroller.
