you can omit the UDP send part and activate Serial instead for debugging.

Hi,

Here is the sensor https://www.dfrobot.com/blog-735.html


It works perfectly with Arduino boards.

With ESP32: I tried, sensor pins, ADC pins, I2C pins (one at a time) without success.

Hi,


Even with https://dl.espressif.com/dl/package_esp32_index.json, https://dl.espressif.com/dl/package_esp32_index.json, http://arduino.esp8266.com/stable/packa ... index.json


ESP32 by espresif does not appear in the manage library window.
