ESP-WROOM-32

[espnoob]

Santa brought me a ESP-WROOM-32 because I would like to make a salt-level-indicator. I thought I could easily follow the instructions found here https://adonno.com/salt-level-sensor/

But : I cannot find a 5 volts output and whats more confusing ....my esp has two rows of pin holes on both sides

So can some of you tell what row to use and where to find the 5v output ? Or did I ask Santa for the wrong hardware ??

Thanks in advance

The site you are linked are especially using ESP8266 D1 Mini. The image you posted is an ESP32 D1 Mini Pro it is not the same. ESP32 Mini has double row pin hole on both sides and VCC near the 3V3 has to be the 5V. Altough firmwares for the ESP8266 is not compatible with the ESP32 as this is not the same hardware.

Well this proves I am a complete noob. Short: I can not use this for the salt level indicator ?

I guess you can, slightly changing the config file to use ESP32 instead ESP8266 in ESPHome.
But this is not the ESPHome forum, this is the ESPEasy forum. I've never used neither ESPHome, nor Home Assistant.
