Really well deserve among so many top global trainer

[PSISVarshiniKN]

U explained very well sir thank you ...

[PSISVarshiniKN]

I sincerely appreciate your help with the project today sir even u don't know who am I . Thank u for helping me to accomplish my goal. I wanted to express my gratitude for your training today.You are the best.I wish you the best of the best with your career and your life.God Almighty will continue to favour you and crown all your efforts with success...!.i can't express ur help in words sir thank you so much.

As per the circuit diagram how do i connect the 12v dc adapter to node mcu 8266 vin?

[akinaaisyah]

hi sir how do you recommend the safest way to use external 5v from node mcu esp8266 to the pH sensor

[watchyoutube]

Great video man. But how do you connect the ESP32 board to the ph sensor? I didn't get it.

[capstonegroup]

Sir is it possible if you will add email notification here? That when the reading of the sensor is lower than 5, it will notify the user?

[hanfan]

have you used battery on circuit diagram

[amulya_minnie]

Hello sir, I'm trying to build a project using ph. But I'm having a difficulty with the code. Can you please help. I connected a motor pump to the esp along with ph sensor. So when the ph sensor value decreases the motor pump should turn on. In the code I tried to implement if else but i am getting an error saying "conversion from int to constString is ambiguous"
Can you please tell me a solution sir ?

[blynkappli]

Hello sir, I am using ph sensor, arduino, nodemcu and blynk. I am having trouble with the codes for nodemcu. Can I ask for your help sir ? Thankyou

[klicks]

My voltage/PH from the ph sensor is hard changing from 6.87-7.3
But why ?
The input voltage from the arduino are 5Volts constantly. Please help
I need to measure 24/7 but sometimes the ph value are to high or low

[wharrjk]

what version is that node mcu esp 8266

i am getting this error how can i resolve it, i have already define the both but getting same error again again

[miavega]

Hello I've done all of these but the readings on my Ph sensor is above 14. What seems to be the problem?

[yumamotokirara]

sir when im trying to add my device to blynk my esp32 wifi keeps disconnecting

[yogeshwargupta]

what is blynkEdgent.h
it is not present in my library manager
please explain about it and how to include it

[Anand.M]

Hi, I need to build this ph sensor. Could you please help me on this project. I’m not an expert on this topic. Need your support. How may I contact you.

[lukemarkg.carino]

Hello sir, I am using the ESP WROOM 32 board. I want to ask what should I define in my code. In your case, you use NodeMCU board so you put #define USE_NODE_MCU_BOARD

[djontuf]

I am using esp8266 nodemcu. But i got this error sir. Help me sir. Need this for my uni project

[capstonegroup]

Hello sir, can you help me with my project. I did all of these but I cannot connect the blynk app. It only appear the readings on my serial monitor
