How to use the Arduino Soil Moisture Sensor

Learn how to use the soil moisture sensor with Arduino. This video will cover the sensor basics, sensor pins, how to connect to Arduino, how to program in Arduino, and testing. We'll also go over an alternate connection method to extend the life of the soil moisture sensor, and will even test the working current of the sensor.

I enjoyed the video. I have a question though, how do i show if the sensoe is working using a simulator. For example tinkercad

[@raghavkrishna1690]

I have see that for more complicated projects, they use a breadboard and display. Can I use this is itself? Will the sensor last long

[@nj1204]

Hello, I have verified all connections between Arduino Uno, 485 and NPK sensor, also made sure NPK sensor's power wire is connect to 12V DC power source, the code also looks correct with the same address value as in the manual, but it still always gives 255 value for All N, P K values. Any suggestion how I could resolve it?

Thank you brother it workes🎉 brother thanks a lot

[@babsolaiya3573]

what other way can one connect this small pcb that has the potentiometer on it can anyone use this and apart from the arduino unit how else can the probe be used

[@DesertVox]

Is there a way to 'ruggedize' the probe itself, i.e. the metal plating that goes into the soil, because I've read that it deteriorates with time.

[@minime9400]

It's not possible, this method depends on contact. You wanna use a capacitive sensor instead.

[@titanbrothers5480]

you didnt gave pinmode in analog one and also didnt define moisture at the beginning like you did with sensor state why?please as fast as you can.

Coding for soil moisture sensor?

@@diyengineers can you help me in my project

[@kurtdecena8681]

Hi it is possible with this code i can connect in blynk app? I have node mcu 8266 v3

[@a.irobotics]

yes, i have too

Do you know Arduino programming
Can you do Arduino programming for me I will pay your fee online

[@diyengineers]

Hi Sonu! Thanks for watching. I already show the code on this video. You can just copy and paste.
