Circuit Schematic Ultrasonic Water Level Controller using 8051

Eltronicschool. - There are many application when we using ultrasonic system in electronic controlling. One application that will showing in this time is water level controller using ultrasonic module based on 8051. In here we will show you one of the electronic circuit schematic design for Ultrasonic Water Level Controller using 8051. One ultrasonic module that used in this application is HC-SR04 ultrasonic ranging module.

Component Parts
  1. HC-SR04 ultrasonic ranging module
  2. AT89S51
  3. Trasistors
  4. Capacitors
  5. Resistors
  6. X-Tal 12 MHz

Circuit schematic like in figure 1 above is circuit schematic Ultrasonic Water Level Controller using 8051. A simple water level controller using ultrasonic  range finder module and 8051 microcontroller is discussed in this article.Many projects based on ultrasonic range finder and water level controllers have bee already discussed here. This is just another application of the ultrasonic ranging module. This water level controller can monitor and control water tanks up to 2m deep and the accuracy of measuring is as low as 1cm.  Since no mechanical float switches or electrodes are used here, there will not be any mechanical wearing or corrosion and this makes the system highly reliable. Any way proper care must be given to insulate the ultrasonic ranging module from damping as it contains a lot of electronics. 

And now you can read more about the circuit schematic working from HC-SR04 ultrasonic ranging module and you also can write the 8051 listing program of ulltrasonic Water Level Controller using 8051 using link here.

Thank you for your coming here in site, we hope the article above will help you to know more about your an electronic circuit design and software in this time, etc. Please comment here when you want to share and other. Thank you.


  1. The water tank special side by side mounting brackets (made of Aluminum or Galvanized steel) used together with the special strips lets you to firmly mount the water tank to the UTV.
