Connected Garden Project

This project was developed as part of our 4th year of engineering studies in electronics and embedded systems. The project was carried out by a team of two members: @Kevin-Pottier. and @Joliaus. The system leverages the NRF52 microcontroller and various sensors to create a connected garden solution with PWM control, environmental sensing, and mist generation.

Project Overview

The goal of this project was to design and implement a connected garden system using the NRF52 microcontroller. The project features environmental monitoring, GPIO control for peripheral devices like a brumisateur (mist maker), and light intensity measurement using the VEML6030 sensor.

Key Features

• PWM and GPIO Control: Controls peripherals such as a brumisateur (mist maker).
• I2C Communication: Interfaces with sensors like the VEML6030 for light intensity measurement.
• Modular Sensor Integration: Designed for additional sensors for enhanced monitoring capabilities.
• Wireless Connectivity: NRF52 provides Bluetooth Low Energy (BLE) communication for remote control and monitoring (if implemented).

Components Used

• Microcontroller: NRF52
• Sensors:
  • VEML6030 (Light intensity measurement over I2C)
  • Additional sensors (optional based on project configuration)
• Brumisateur (Mist Maker): Controlled via GPIO for on/off states

Getting Started

Prerequisites

• Development Environment: Nordic Semiconductor's nRF Connect SDK and tools.
• Hardware: NRF52 development kit, VEML6030 sensor, brumisateur, and necessary power supply.
• Dependencies: Ensure the correct libraries for PWM, I2C, and GPIO control are installed.

Installation

1. Clone the repository:

   git clone https://github.com/Kevin-Pottier/Projet_OC.git
   cd Projet_OC

2. Build and flash the code onto the NRF52 microcontroller using Nordic's development tools.

Usage

• Brumisateur Control: The system includes functions to turn the mist maker on and off via GPIO.
• Light Sensing: Light intensity data is acquired using the VEML6030 sensor over I2C communication.
• PWM Control: Implemented for additional control functionalities.

Contributions

• @Joliaus.: Focused on hardware integration, sensor configuration, and system design.
• @Kevin-Pottier.: Implemented software development for GPIO, I2C communication, PWM control, and project documentation.

Future Work

• Expand the system with more environmental sensors.
• Add wireless connectivity for remote monitoring and control.
• Optimize power consumption for longer operation.
