Problem relating firmware version and soil sensor installation
Hallo,
i think i have got a problem relating firmware. I can' t install normal firmware for my esp32. I am configuring a soil sensor, following this youtube video https://www.youtube.com/watch?v=oty_kwsHpo4&t=410s. I tryed with different kind of soil sensor but i have got ever the same problem, i can't read nothing, ever the same result (zero). So i think that could be a problem relating the firware. i see that in the video he uses a normal version of firmware. I am tryng to installa a normal version for my esp32, but i can't find the file factory.bin for normal installation. How i can do this? any suggestion?

Re: Problem relating firmware version and soil sensor installation
The "test" build has all included in the "normal" build + some extra plugins.
Since the partition for the bin file on the ESP32 is larger than the one on the ESP8266, there is no need for a "normal build" for ESP32.
Can you give a schematic drawing how the sensor is connected to the ESP?

Re: Problem relating firmware version and soil sensor installation
MainBoard is: Esp32-wroom-32
Firmaware is: ESP_Easy_mega_20200608_test_ESP32-wrover-kit_4M316k
The soil sensor is: https://www.amazon.it/iHaospace-Capacit ... 62&sr=1-15
PIN Connection:
1-GND to GND
2-vcc to 3V3
3-aout to GPIO13
this is the screenshot of DEVICES menu
serial monitor

Re: Problem relating firmware version and soil sensor installation
Why the WROVER kit build?
That one is meant for a board which I dare to say you probably don't have.
Why not the "standard" ESP32 build?
Also don't use a GPIO pin on the ESP32 which is connected to ADC2.
ADC2 cannot be used when you also use WiFi. See: https://docs.espressif.com/projects/esp ... s/adc.html
As a matter of fact, I'm quite surprised I don't see a warning for this fact in the screenshots you show as I'm quite sure I planned to add those warnings... somewhere.

Re: Problem relating firmware version and soil sensor installation
now i am using this firmware: ESP_Easy_mega_20200608_test_ESP32_4M316k - is it the normal?
which pin i have to use on my esp32 board?

Re: Problem relating firmware version and soil sensor installation
As you can see in your own screenshot, just pick a pin which is labelled "ADC-1" in the screenshot.
GPIO 32 ... 39 can be used and not conflicting with the WiFi operations.

Re: Problem relating firmware version and soil sensor installation
ok, gpio 36, now i receive a number that i don't know what is it

Re: Problem relating firmware version and soil sensor installation
So now you're reading an analog value.
Either you determine 2 points for the calibration, or you use the raw values.
