Distance meter using ultrasonic sensor

Distance measurement using ultrasonic sensor Kit
How it works!!
2
Introduction

• This kit is designed and developed to detect and
  measure the distance of an object in front of
  this device.
• An ultrasonic sensor is mounted on the front end
  of this kit.
• If an object is present in front of the sensor,
  the waves hit the object and are reflected back
  from the object to the receiver port of the
  sensor.
• Thus, by identifying the wave, the time
  difference between the transmission and receipt
  of any particular wave is noted. This helps us to
  calculate the distance of the object from the
  device

Background

• These machines as well as robots have the
  ability to observe its surroundings in different
  forms and communicate the same to a user who
  commands them to take related action.
• One of the basic functions of this smart robot
  is to detect objects or obstacles in front of it.
• An ultrasonic sensor is used to fulfill this
  function as they consume less power and can
  perform efficiently during the day as well as
  night.
• It can be used instead of a camera as cameras
  will be quite useless during the night.

Continued..

• The HC-SR04 Ultrasonic Module has 4 pins
  Ground, VCC, Trig and Echo.
• The sensor produces an ultrasonic sound wave
  from TRIG port at a frequency of 40k Hz which
  travels through the air and if there is an object
  or obstacle in its path, the wave bounces back to
  the ECHO port of the module.
• By obtaining the total travel time and the speed
  of the sound, the distance of the object in-range
  from the sensor can be calculated.
• The Echo pin receives the wave signals which are
  reflected from the object. The Echo pin notes the
  time difference in the emission and receipt of
  sound waves in microseconds.
