I managed to get this working beautifully on a breadboard. So, I ordered 5 of the PCBs from a PCB supplier and they don't work. In the schematic you can see the LM35 pin 3 is connected to the GND of the ESP32. However, in the gerber you can clearly see the trace going not to ground but to pin 13 of the ESP.
I think the pinouts for the ESP that I'm using are different. I could not get the voltage sensor to sense anything then another website said to use pin 32 and when I made that change it worked fine. What ESP are you using for the PCB?
Hi Code is running everything good but getting temp as 329 and it’s constant it don’t change at all neither voltage nor light intensity Getting same output everytime. Checked the sensors looks fine When I check lm35 with multi meter I was getting 25-26 celsius Can you please help me with this. Tried almost everything
Ensure the esp is grounded to the same ground as the LM35. I was getting the same thing, Temperatures in the hundreds then a whole bunch of zeros. ONce I grounded the ESP the reading became normal.
code is running properly with no error!! but nothing is coming on LCD and when i press the buttons on esp32 the lights on lcd changes but not getting any output
Nice tutorial. Great Project. In real solar applications. I want to do things like check my battery percentage. Check how much load is on my system And Probably detect excess load on the batteries. Please can you do a tutorial on that? 👍

This is awesome. Thanks for uploading.
Another great project 😃😃
Thank you so much for consistently sharing the knowledge with us 🤩❤️
Amazing project

any project with IOT and machine learning
Good project
But
Light intensity Gmail alerts would be great
plz send the code and also brief drivers required to work on esp32
Nice work!
kindly send the full code plz it's urgent the code on website has issues in compilation
Great project.
Good project 👍❤️
This is awesome

Check the connection of LM35 with analog pin. Run an example code to verify whether ur LM35 is fine.
Ensure the esp is grounded to the same ground as the LM35. I was getting the same thing, Temperatures in the hundreds then a whole bunch of zeros. ONce I grounded the ESP the reading became normal.

How to ground ESP32 ?
@@jazibhassan1526 run a cable from the ground of the ESP32 to the ground of the temperature sensor. The 2 devices need to share a common ground.
Hello ,
My display is showing 0 volts and and temperature is not changing
Same errror!!
Did you try anything???
Did you found any solution???
Getting the same problem
Did anyone got the solution?
@@eshabhatt4068 check out your Arduino code
There must be some error
Nice project......i have a 2kw solar project and i want watch its power kwh or kw in real time can u make it?
Can u plz let us know the connection tutorial
Can u make ax2358 input selector ic based 5.1 amplifier remote
Do we need to do soldering
What does this mean(Compilation error: no matching function for call to 'LiquidCrystal_I2C::begin()')
Try changing lcd.begin(); to lcd.init(); The LiquidCrystal_I2C has no begin function.
HEYYY PLEASE TELL ME HOW TO USE THINK SPEAK SERVER? I M IN TROUBLE PLEASE HELP ME
code is running properly with no error!! but nothing is coming on LCD and when i press the buttons on esp32 the lights on lcd changes but not getting any output
Change your I2C address for LCD. Some LCD has address of 0x27 while some has 0x3F. Change the address in code. Then upload and check.
Try setting the contrast level on the LCD. There is a scew on the back to enable this.
Nice

👍
Some tutorials on this is coming soon. I am working on it.
Can you make this same for my solar system I will buy :-
Parameters are :
Voltage(upto 600v )
Current (upto 100A)
Power etc.
Wifi monitoring
Cane we set the wifi SSID and password
Plz provide me the connections😢
How to buy pcb board
I want this project
I want to contact with you sir
Please respond quickly please
Do you guys ship the models to Canada???
Yes we can ship it to Canada.
How many days it takes minimum if in hurry??
@@HowtoElectronics how can I contact you alternatively if I want the project to be delivered???
I will send you through Canada post.
@@HowtoElectronics max how many days it may take??
Please help me out
