Stemma soil sensors not detected

Post by antitrust311 »

Hello,

I ordered four Adafruit Feather ESP32 boards and they arrived today, four 4-pin JST PH to JST SH Cable - STEMMA to QT cables and four Stemma soil sensors as well as four LiPo 400maH batteries. I have all four sensors programmed, batteries connected to the feather boards and cables connected to the soil sensors. They are all online in Adafruit IO and not a single one of them can detect the soil sensors via I2C. I was following this guide

The boards you have are not Feather HUZZAH ESP32, they are ESP32 Feather v2 boards. Also, the STEMMA-QT connector has controllable power. See https://learn.adafruit.com/adafruit-esp ... er-3122982.

You are correct and I just realized that I had programmed them incorrectly. They are all working now. Sigh
