ESP32 Tutorial 55 - How to measure 12V, 24V or 100V DC voltage | SunFounder's ESP32 IoT Learning kit

In this video we learn how to measure any DC voltage using ESP32 board. we learn how to use only 2 resistors to be able to safely measure the DC voltage using ESP32.

Like + comment because this guy personally helped me with a problem on a +2y video, what a chad

[@oapke124]

Nice video bro! It helps a lot. Can you please publish the code asap, where can i find it?

[@ibrahimaliabbasi5188]

nice

[@bbjodel3778]

Hi Robojax i've an ESP32 WROOM with an WCS1700 how to mesure an voltage from battery 60V max and 70A max ?
Thank for your help you have a code please ?

[@jrapplefan2231]

Also, what is the precision of the reading ?

[@robojax]

10mV

[@jrapplefan2231]

Could we read AC voltage with a small different circuit ?

[@robojax]

if you can convert AC to DC with some circuit, yes it should work.

[@taufiqulrahman5004]

is there any updates fotr codes

[@robojax]

Hi, I am sorry for the delay, the link to the code is added in the description.

[@Thor-dy1xu]

Where' the 'code' ?

[@robojax]

Will be published soon.
