ESP32 and ADS1115 ADC- Voltmeter project
HTML-код
- Опубликовано: 11 апр 2022
- I am using ESP32 , TFT display (240x240) and external 16 bit ADC module (ADS1115) to measure voltage.I I just want to show you my simple voltmeter sketch. I am comparing my project with a real multimeter and results are quite good. I haven done any calibration and no external components are used.
Parts used in project:
ADS1115 Module:

Esp32 development board: www.banggood.com/custlink/vG3...
TFT Display 240x240 :

Code (Arduino IDE) : github.com/VolosR/ESPADS1115
Library: github.com/terryjmyers/ADS111...

Very nice project and I like how you display the values. Very elegant.
Thank you :)
Gorgeous Fluke Voltmeter, as always an awesome projekt
Thank you for another great little project. I am making a solar power monitor and always learn a lot from your code.
Tnx Gordon, i always wanted to male solar monitor, do you know way how to monitor power output of panel?
@@VolosProjects Lookup Adafruit INA260, it can sense +-36V and 15A. I use it with a 200W panel (10A short circuit current).
super nice esp32 project 🤩 I would like to monitor a sensor 0 to 10vdc and display the result on a cell-phone using remoteXY Bluetooth.
I wish there was a esp32 module with better analog conversion and isolated would be even better all on one board. 🤔 thanks a lot for the great info. 😎
I'm always impressed by our graphics design using these tiny screens :) Is there already a video where you go into details what your workflow is coming to this results and use them in your code?
No, right now i dont have video about design, but i can do that, tnx for idea.
@@VolosProjects that would be highly appreciated - your graphic designs on these tiny displays is just awesome 🥰 rgds, Mike
Like the screen design.
I guess the ADS1115 have differential inputs. That's also nice to have.
Your graphics make my iPhone look like a ZX81 :)
hahah, tnx :)
I'm sure it's his day job making UI so pretty! 😍
he has a nice feel for colours an their temperatures ++Rep
Amazing 👍👍
@Volos Projcts "Hello, thank you very much for sharing your projects! They help me learn alot about basic electronic programming (I am a beginner). My question is, could I measure based on diodes with this project, by modifying it? Could you perhaps make a variation?
Greetings from Peru."
wow, cool thing~👏👏
Hi thank you for this, I have made it but my display flashes at about half second intervals? The picture is solid, just the digits. I have spent two days and cannot find the reason have you any idea to help me please? Anyone? Bob. UK
How can I measure reverse voltages? I want to measure the voltage drop over a shunt resistor and it has to be both when charging and discharging a battery
Great Vid! What is that gray wire running from the ADC to the TFT?
i wounder if the ADC is better in the newest versions of ESP-32 ...like the S3 or C6 versions
Are the SDA and SCL pins at different voltage levels between the ADS1115 and the ESP32? I don't know if those pins on the ADS1115 are considered output, input, or both. I was thinking both. So I thought the pins on the ESP32 are not supposed to exceed 3.3 V?. Although I have accidentally hooked up 5 V signals to the ESP 32 pins and it seemed to be OK.
great Video an your other projects :-) have a simple question: if I need no +/- range, but a range from 0V to 2,5V with the best resolution of the ADS1115. I dont know, I have to programm this effect. 0V to 2,5V shout be a digital value 0 to 65536. Is that possible?
Hi. Thanks for sharing. Can you make a Rpm Counter please? Or is there a small module like this that I can use to make an RPM counter?
Excelente proyecto, me encanta la gráfica del display... Eso con un micro STM32 es posible manejarlo, o tiene poca memoria, digamos un 030? Cómo el de la Bluepill. Saludos desde Córdoba Argentina
🆒 Excellent video! Thanks from whole 🇵🇰
Cheers from Croatia
Great video thank you
Hello, what software were used to make the pictures used in your project? Can you provide a tutorial? For example, the picture of fluke
I'm looking to do something similar i need some help im looking to measure up to 3V max but I need very accurate resolution down to microvolts is is possible with esp32 s3?
Thank you!
Awesome !!
Could you explain why are you using 32752 in the code instead of standard 32768 for this ADC ?
hi do you mind sharing your schematic connections for this project?
Great video....can you consider doing a easy and reasonably accurate current monitor using a resistor type shunt. The ESP32 is not good at doing this and the ADS1115 is a cheap very good module
I like your channel.
Can you please try with the zmpt101b voltage sensor?
hey man how small can you make the battery supply for a display of this size? i want to make a project that is very compact :) thanks for inspiring me!
Very cool
Hello, :-) where can i get the FLMUKE R20XTW? Is this a real Multimeter or only a 240x240 Display? Thanks
Excelente video. Saludos
Thank you my friend.Saludos
👍
Magin connecting two of these to perform a smb...
Very nice!! Can you measure AC voltage and / or frequency with same equipment?
Or you can make a diagram or tell us which contact to connect where.
Thx Sir! always nice designed Displays and a charming English Accent nice made tutorials! As I am reacting to your video in 2024 what do you think about: ESP32 AI / Rust / ESP P4 / most important I think:😎"Matter for IoT"? -What are Your predictions? What SoC is your favorite for the future and which language... Danke!
Thank you! To be honest i dont have prediction, in case of microcontrolers low level lenguage will always be best option, so i dont se anything will replace c lenguage soon, there are python options but for my needs python runs way to slow on board with display on it. AI is another story, it can help but you will still need to know what you are doing. I cant wait ESP P4 :)
Thanks! No special needs from my side Im just fascinated wat is possible now on alow cost base. Always looking for new input°° 😎@@VolosProjects
PS Nerver use a blue bridge cable for a Positive Jumperline as you showed in 6min12. LOL Why? out of cables? No Front -just funny. Please keep on creating.
Mr velos I think you are skillfull . I need your help making a moon tracker. So the watch user can determine if moon is in Scorpio. When rumours start is when moon is in Scorpio. I need wizard watch
what is the highest voltage you can measure without voltage devider ?
3.3 v
Is it fast enough to make an oscilloscope?
Better try a 2040. But is an i2c scanner pretty nice
10 multimeter ??
The code is compatible with Arduino board??
I am not sure, probably it will work but slower
FLMUKE 😄
What about voltages less than zero?
It's a unipolar ADC, so no.
The more I try to use wifi microcontrollers with my analogue sensors, the more I end up switching to RaspberryPi/ADS1115 combo.
mogo bi sledeci projekat da uradis merenje struje sa nekog senta
inache na mene si zaboravio
a tvoj skec za merenje otpora
mi javlja sledecu gresku
TFT_BL' was not declared in this scope
i istu gresku mi javlja jos na nekom skecu
a to je sve ranije radilo
kako zasto
misterija
samo meni mogu da se dese takve nebuloze
ono oko tastera sto sam sjebo je tvoja krivica i tvoje zarazne igrice 🙂malo sale naravno
pozdrav
Pozdrav, imas starju verziju tft_espi library, samo napravi update i trebalo bi te prestat zafrkavat, ili jednostavno umjesto TFT_BL napisi "5"...proucio sam i dalje mi nije jasno zasto tvoj ttgo ne radi. Vidis da sam prestao radit igrice, ljudi lome skupe igračke :)
@@VolosProjects nazalost isto sve
razlika je samo sto se upali pozadinsko osvetljenje ali prikaz nista
i opet kad upucam stari skech sa logo od ttgo to radi
doduse nije skec nego bin fail
nista ovaj ostaje da radi kao obican esp32 i kraj
hvala ti u svakom slucaju
sta mislis esp32 kao jel moze da sluzi zaq chitanje napona sa shenta
75mV
pozdrav
@@VolosProjects znam da sam dosadan
ali tako je sa ovima sto su preko 60god
radi modul sad a kako treba
zez je bio sto kad sam ja napravio update librari tft:-espi
trebalo je ponovo one modifike u onom setup failu
luda noc u podne
a malo je falilo da zavrsi u sporetu
hvala ti puno na pomoci i vremenu
@@djokinac aha, ajde sva sreca da si uspio. Ovi moduli bas postali preskupi, steta bi bilo da ide u sporet.
@@VolosProjects ma ako covek ima neku korisnu namenu i nije skupo koliko su dobri
imaju velike mogucnosti
ali ja ni za st apametno ne koristim
eto jedan sam sjebo prvo testere
zezam se da je tvoj akrivica
a posle je crko
sad kad ga ukljuchis pochne odma da se greje sam chip
daj mi neku dobriu ideju za st ada ga koristim
pozdrav
esp 32 have worsest adc in history of microcontrolers. use it to find it
FLMUKE 😅😂😂😂
