IoT Based Solar Power Monitoring System with ESP32 & ThingSpeak Server

[@RandomTorok]

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.

This is awesome. Thanks for uploading.

[@RandomTorok]

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?

Nice work!

Amazing project

Great project.

Good project But Light intensity Gmail alerts would be great

[@iotprojectsideas]

This is awesome

[@eshabhatt4068]

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

[@HowtoElectronics]

Check the connection of LM35 with analog pin. Run an example code to verify whether ur LM35 is fine.

[@RandomTorok]

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.

​@@RandomTorok How to ground ESP32 ?

[@RandomTorok]

@@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.

Good project 👍❤️

Do we need to do soldering

Nice project......i have a 2kw solar project and i want watch its power kwh or kw in real time can u make it?

Hello , My display is showing 0 volts and and temperature is not changing

[@eshabhatt4068]

Same errror!! Did you try anything???

@@eshabhatt4068 check out your Arduino code There must be some error

[@khadejaziauddin1476]

plz send the code and also brief drivers required to work on esp32

HEYYY PLEASE TELL ME HOW TO USE THINK SPEAK SERVER? I M IN TROUBLE PLEASE HELP ME

[@eshabhatt4068]

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

[@HowtoElectronics]

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.

[@RandomTorok]

Try setting the contrast level on the LCD. There is a scew on the back to enable this.

[@jagadeshjagadesh3864]

Lcd Display is not working

[@user-pq6bf4qn6p]

What does this mean(Compilation error: no matching function for call to 'LiquidCrystal_I2C::begin()')

[@RandomTorok]

Try changing lcd.begin(); to lcd.init(); The LiquidCrystal_I2C has no begin function.

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? 👍

[@HowtoElectronics]

Some tutorials on this is coming soon. I am working on it.

[@MedicalDetective-sw4fx]

Can you make this same for my solar system I will buy :- Parameters are : Voltage(upto 600v ) Current (upto 100A) Power etc. Wifi monitoring
