ESP32 and ADS1115 ADC- Voltmeter project
Переглядів 46,161
2 роки томуI 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...

Gorgeous Fluke Voltmeter, as always an awesome projekt

Thanks. I’ve ordered the parts. This will help me learn Arduino sketch much more. It is confusing and I’m used to being able to single step through the program in visual studio which I’m also trying to learn. Information overload but this focused project is perfect. Well done.

@@VolosProjects Lookup Adafruit INA260, it can sense +-36V and 15A. I use it with a 200W panel (10A short circuit current).

@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."

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. 😎

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?

i wounder if the ADC is better in the newest versions of ESP-32 ...like the S3 or C6 versions
@deterdamel7380 2 роки тому
I guess the ADS1115 have differential inputs. That's also nice to have.
@happyhippo4664 Рік тому
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.

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 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

Only small AC voltage at a frequency determined by the A/D converter sampling frequency and maximum voltage.

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!
@VolosProjects 2 місяці тому
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 :)
