ok this is unexpected. Everywhere I see on forums, they say it's impossible to read two values on the same analog pin. Your idea is great, it works fine because the nodeemcu is super fast. I will try this and give feedback.
Great info, Ive ordered several wemos boards because they're cheap and and I need them for simple sensor logging/alarm but I didn't know they only come with 1 analog pin. Not bad purchase afterall 🙂
hi, can we connect ph sensor and tds sensor through the diode, then what about vcc pin how we can pass voltage to respective sensore. can you explain it in small sentence.... thank you
@@EDISON_SCIENCE_CORNER My sensors work with 5v and the esp8266 only have 3.3v power. Currently, I use an external 5v power supply to power my sensor with common ground connected to esp8266. Would I be able to use your method with an external power supply for my sensors? Thank you
@@EDISON_SCIENCE_CORNER I have tried with transistors but I really struggled to get it to function with a stable reading. Do you perhaps have an example of how you achieve this? I tried using a 2222A and also a ksp 44 c20 as I had some laying around

Awesome explanation bro. Only suggestion is, please use jumper cables on breadboard instead of soldering.
Thanks. Understood. but i soldered to get precise values.

One more video coming on this subject🤗
Little wrong, as Diode forward bias voltage 0.7 to 1 V would come in picture, so you wont be able to read lower values.... Use relay instead !
Yes thats true
You´re right!
Thank you bro, you just save my money, love from Pakistan
Keep supporting
I am using turbidity & TDS sensors for project. So digital pins should be connected to which pin of these sensors?
You can use any digital pins for that
Thanks, really helped me 🙏 .
😍🙏
how do you read 100 analog inputs twice per second with esp8266
100?
100... For example if you want to read each cell voltage in a 100S pack, using voltage dividers
Isn't there a voltage drop caused by the diode?
Yes
Really helpful thanks!
Welcome sir
Thanks
Ha bro
Is the diode obligatory ? I tried without it it gives wrong results , plus can u tell me what diod should i buy ? Thank yoy
Should use diodes. Without that it will not work.
Great tutorial!
Thank you
GENIUS.
Not yet
Thank you so much
Stay tuned
hi, what are the specifications for these diodes. Even it doesn't play a huge part, what range for diode specifications do you recommened?
IN4007
smart and clever...:) how about connecting the esp8266 to a smartphone? thanks...🤤
What you want know about connection
can I use an LDR and a soil moisture sensor on AO pin and it won't result to power issues
Yes we can
What is the specs of potentiometer?
10k
Great. So we don’t need to flash esp8266 with any firmware????
What you mean
can it be use for ph , turbidity & conductivity sensors?
You can use any sensor check my recent video about this subject
If the Blynk coding is omitted or monitoring is done only through the serial monitor, does it affect the voltage reading or not?
Blynk code just for demo. One more video available in my channel check it.
hi, can we connect ph sensor and tds sensor through the diode, then what about vcc pin how we can pass voltage to respective sensore. can you explain it in small sentence.... thank you
Yes we can use just like this please watch my new video there is one more video about this subject
Hey thanks for valuable response, can you share link of mentioned video, I'm not able to find.... thanks
If I use 3 different types of gas sensors do I have to use diodes too and is there a program change? Thanks
Yes you have to change the code
Can I measure two types dc voltage using dc sensor with this method ?
Nooo
@@EDISON_SCIENCE_CORNER oooo
If i want to use 4 gas sensor (MQ4, MG811, MQ131, and DHT11), can this method be used?
Yes you can use this method for analog sensors and you can connect DHT 11 sensor to any digital pin
Okey, thank u🙏
If i use modul analog multiplexer, can this code be used? 🙏
Can you make this project in Arduino iot cloud ☁️
Yes we can
Can we use both sensors at a time..?
Yes
Sir please add video for simple function generator
Oh yes will try
I would like to give your project a try. Regarding the diodes, does it require a specific diode? Which did you use?
Thank you
Go on. Use 1N4007
@@EDISON_SCIENCE_CORNER I have two of those diodes so I will test them. thank you

Use a trasistor driver

Can i connect a analog joystick with nodemcu.
If yes plz guide.
Yes it is possible
@@EDISON_SCIENCE_CORNER please make a video on it so i can make it
What are the specifications for the diodes used ?
1N4007

is this make any problem to nodeMCU
No no problem
pin D1=4 and D2=5 meaning?
Gpios
@@EDISON_SCIENCE_CORNER But D1 is 5 and D2 is 4 actually
