ESP32_Adafruit_STEMMA_Soil_Sensor_Example

Introduction

This is an example application for the Adafruit STEMMA Soil Sensor, an I2C-capable sensor that measures both moisture and temperature.

It is written and tested for v3.3 of the ESP-IDF environment, using the xtensa-esp32-elf toolchain (gcc version 5.2.0).

Ensure that submodules are cloned:

$ git clone --recursive https://github.com/Krzyshio/ESP32_Adafruit_STEMMA_Soil_Sensor_Example.git

Build the application with:

$ cd ESP32_Adafruit_STEMMA_Soil_Sensor_Example.git
$ idf.py menuconfig
$ idf.py build
$ idf.py -p (PORT) flash monitor

The program should detect your connected sensor and display readings on the console.

Dependencies

This application makes use of the following components (included as submodules):

• components/ESP32_Adafruit_STEMMA_Soil_Sensor

Hardware

To run this example, connect the STEMMA Soil Sensor to two GPIOs on the ESP32 (I2C SDA and SCL).

Features

This example demonstrates the use of the ESP32_Adafruit_STEMMA_Soil_Sensor component. It demonstrates:

• Sensor initialization.
• Reading of moisture and temperature.
• Error handling and reporting.
