    You just need to change a few lines of code. Check the code I have given above from line 41.

    You can send me a private message through hackster. I entertain all your doubts.

    For this model, I have used submersible pump. But you can use any small water pump if available.

    Arduino uno
    Ultrasound sensor
    Motor driver for pump
    Pump
    Message me if you require any more assistance.

    Really looking forward to view your project. Best of luck with that

    I totally agree with you that the surrounding of the tank will damage the sensor. This system has its disadvantages and this is one of them. It is not suitable for high temperature applications. But we surely can use it in normal temperature liquid and this system is also more suitable for water level detection in domestic sectors.
    Thank you for your comment!!

    Actually I had made this project for college presentation, so for presenting I had to use 100 photons.
    And the photons requirement changes as per the plant. I had use the specification of a lettuce plant, which requires around 250 photons. If you are planning to use some other plant you need to do a research study of the plant. You can refer https://scholar.google.co.in/
    Feel free to ask for help anytime. Glad you liked it.

    Hello Jenovauh, I am sorry for confusion. I couldn't find any 230V supply in fritzing and a bulb so i avoided that part. You can use a SPDT relay of 5v with your arduino. The circuit diagram of spdt relay is available of net.

    The diagram i have created is a rough drawing, therefore you can connect with any analog pin and assign whichever you are comfortable with.

    And for the light sensor's value to convert into photons per second i have used the following formula which was available on the net.

    float ldrdata=analogRead(A8);
    float resistorVolt=(1024-ldrdata)/1024.0*5.0;
    float ldrVolt=5.0-resistorVolt;
    float ldrResistance= ldrVolt/resistorVolt*5000.0;
    float lux = (12518931)(pow(ldrResistance,-1.405));
    float photons= lux
    0.019;

    You can use any light sensing device whichever is available.
