Yes, there is a video which shows every single step: youtube.com/watch?v=T_tpKoNCVYw

i wanted to know if there will be any changes in the values if the input voltages differ

Phil, I am new to this.
Can we add 5Volt mini water pump?
When dry – it turns pump on UNTIL sensor detects water then it turns off water pump?

If so, is there a video to show EVERY STEP building it and how to add code to Arduino?
Also list of every item needed and website to order it?

I am DISABLED BUT CAN FOLLOW GOOD VIDEO OF EACH STEP.

OR I AM WILLING TO PAY SOMEONE TO SET UP SOME FOR MY NEEDS.
EMAIL: altonddavisjr(at)yahoo com.
Most Humble Appreciation
Alton

Thank you Sara.

I appreciate your kind help and advice

Hi.
You don’t need a library because this is an analog sensor.
So, you just need to read the data pin using the analogRead() function as shown in the code.

Sara

I am a newbie on the Arduino stuff. I have seen that for other sensors you are required to upload a library; I did not see any link anywhere to a library for this sensor, is it not required for this one?

Hi.
I haven’t tried it. Do you?

Have you tried that? To avoid corrosion I intend to use stainless steel screws as electrodes.

Hi Terry.
That module has a potentiometer that sets a threshold. The module will output a HIGH signal (1) if the readings are above the threshold set with the potentiometer. It will output 0 if the readings are below the threshold. However, you can’t “see” what is the threshold. You have to rotate the potentiometer and experiment with several types of soil humidity values to check the best threshold.
Alternatively, you can use the analog readings and set your own threshold value on the code.
I hope this helps.
Regards,
Sara

Hi.
Two measurements won’t give you an accurate calibration curve.
I would recommend that you take more measurements. However, the number of points will depend on the desired accuracy.

Sara
