Seed Incubators and Oven Controller

This repository contains the source code for three projects to control seed incubators and a seed oven using the ESP32 microcontroller.

Projects

• Simple Seed Incubator: Controls a single seed incubator with a DHT22 temperature sensor.
• Double Seed Incubator: Controls a double seed incubator with two DHT22 temperature sensors, one for each chamber.
• Seed Oven: Controls a seed oven with a MAX31865 temperature sensor.

Features

• Remote Control: The incubators and oven can be controlled remotely via a web server. The server can be used to set the desired temperature and to monitor the current temperature.
• Offline Mode: If the WiFi connection is lost, the devices will continue to operate in offline mode, using the last set temperature or a default temperature.
• OTA Firmware Updates: The firmware of the devices can be updated over-the-air (OTA) using Firebase.
• Temperature Control: The devices use a PID control loop to maintain the desired temperature.
• Hardware: The projects are based on the ESP32 microcontroller. The temperature sensors used are the DHT22 and the MAX31865. The heaters and coolers are controlled by relays.

Software

• PlatformIO: The projects are built using the PlatformIO IDE.
• Arduino Framework: The code is written in C++ using the Arduino framework.

Getting Started

1. Clone this repository.
2. Open one of the project folders in PlatformIO.
3. Create an env.h file in the src directory of the project with the following content:

#define SSID "your_wifi_ssid"
#define WIFIPASS "your_wifi_password"
#define API_KEY "your_firebase_api_key"
#define USER_EMAIL "your_firebase_user_email"
#define USER_PASSWORD "your_firebase_user_password"
#define STORAGE_BUCKET_ID "your_firebase_storage_bucket_id"
#define FIRMWARE_PATH "firmware.bin"
#define FIRMWARE_VERSION "1.0.0"

4. Build and upload the firmware to your ESP32 device.
