Ultrasonic Sensor Module HC-SR04 is commonly used with both microcontroller and microprocessor platforms like Arduino, ARM, PIC, Raspberry Pie etc. The following guide is universally since it has to be followed irrespective of the type of computational device used.

Power the Ultrasonic Sensor Module using a regulated +5V through the Vcc ad Ground pins of the sensor. The current consumed by the sensor is less than 15mA and hence can directly power by the on board 5V pins (If available).

The Trigger and the Echo pins are both I/O pins and hence they can connect to I/O pins of the microcontroller. To start the measurement, the trigger pin has to make high for 10uS and then turned off. This action will trigger an ultrasonic wave at frequency of 40Hz from the transmitter and the receiver will wait for the wave to return. Once the wave is returned after it getting reflected by any object the Echo pin goes high for a particular amount of time which will be equal to the time taken for the wave to return back to the sensor.

The amount of time during which the Echo pin stays high is measured by the MCU/MPU as it gives the information about the time taken for the wave to return back to the Sensor. Using this information the distance is measured as explained in the above heading.

Features:-

main features of Ultrasonic Sensor Module are like as below

  • Operating voltage: +5V
  • Theoretical  Measuring Distance: 2cm to 450cm
  • Practical Measuring Distance: 2cm to 80cm
  • Accuracy: 3mm
  • Measuring angle covered: <15°
  • Operating Current: <15mA
  • Operating Frequency: 40Hz

Ultrasonic Sensor Module Applications:-

below are major application of Ultrasonic Sensor Module

  • Used to avoid and detect obstacles with robots like biped robot, obstacle avoider robot, path finding robot etc.
  • Used to measure the distance within a wide range of 2cm to 400cm
  • Can use to map the objects surrounding the sensor by rotating it
  • Depth of certain places like wells, pits etc can measure since the waves can penetrate through water

 

Ultrasonic Sensor Module Pin Configuration:-

Number Name Description
1 Vcc The Vcc pin powers the sensor, typically with +5V
2 Trigger Trigger pin is an Input pin. This pin has to be kept high for 10us to initialize measurement by sending US wave.
3 Echo Echo pin is an Output pin. This pin goes high for a period of time which will be equal to the time taken for the US wave to return back to the sensor.
4 Ground This pin  connected to the Ground of the system.
