This is an open-source IoT project designed for a single-board system like ESP32. The project manages Wi-Fi connectivity, sensors, relays, and user interaction via an LCD and keypad. It demonstrates a clean architecture suitable for small-scale IoT applications, with potential scalability for larger systems.
- Wi-Fi Connectivity: Connects to a network using user-provided credentials.
- Sensor Management: Reads and processes data from various sensors (e.g., temperature, humidity, light).
- Relay Control: Manages relays to control external devices.
- Extensibility: Modular design for adding new hardware or features.
- Hardware: NodeMCU-ESP32 or similar microcontroller.
- Software:
-
- MicroPython - Python 3.8+
- Thonny IDE or any MicroPython-compatible IDE.
- Libraries:
micropython-paho-mqtt,micropython-urequests
- Clone the Repository:
git clone https://github.com/TechOnIt/single-board.git cd single-board - Install required Python packages
pip install paho-mqtt
- Flash MicroPython firmware to your board (if not already done):
esptool.py --chip esp32 erase_flash
esptool.py --chip esp32 write_flash -z 0x1000 esp32-20220117-v1.18.bin
- Upload the project files to the board using Thonny or another supported method.
- Power up the board and connect it to a computer or power source.
- Configure the Wi-Fi credentials through the menu system displayed on the LCD.
- The device will connect to the MQTT server and begin publishing sensor data.
- Monitor sensor readings and control relays remotely through MQTT.
