How to make a plant watering system with the Nodemcu ESP8266 board and the new Blynk update

In this video, we will learn how to make a plant watering system with the Nodemcu ESP8266 board and the new Blynk update. For that, I mainly used a soil moisture sensor and a relay module. We can get the moisture values ​​using the soil moisture sensor and we can control the water pump using the relay module.

First of all I wanted to tell you that your videos are very good, thanks for them! I am new in this world and I wanted to ask you the following question, in the video I see that you connect the 5V relay to the Nodemcu ESP8266 that only provides 3.3V, is this possible?

[@rajendrababu9620]

Bro you use npn transistor neither use relay module

[@rajendrababu9620]

Im used npn transistor BC548 it will easily trigger the water pump

May you tell me after uploading the program in esp8266 now we can disconnect the wire from esp8266 from laptop and then we are able to do this using mobile.

[@PMARMYGamerz]

[@gamerofhell6003]

Sir this projects also work like this or not. When moisture level is low then motor automatically start. When moisture level is high then motor automatically off.

[@amoldip2445]

Hi sir, could you please add automation condition in same code for me. Condition is if moisture level < 1 turn ON motor pump and if level is high turn OFF Motor pump

[@rheinnerkj6038]

When the pump has not been connected everything is going well but if the pump has been connected,the LCD will have an error and displays an unclear code, is there a solution?

[@MrQuiet]

Try to not use VIN if u are connected to USB like he does in video and put lcd and senzor vcc at 3.3V pin.That should fix it

Hey I need help, in the one i have built everything is running except the fact that when i click water pump "ON" the motor isn't starting. The only changes i did is i have not used the lcd display so i thought to remove the lines of code which are related to the LCD display. Would it cause the issue ?? Also if it is possible would you send me the code without the LCD display items pls Nice tutorial btw
