Plant Watch

See my plant data here: https://linux.plant-watch.com/

Plant Watch is a smart plant monitoring system that keeps track of soil moisture levels for houseplants using ESP32 microcontrollers and soil moisture sensors. This project aims to explore IoT, microcontroller integration, and self-hosting solutions while providing a practical tool for plant care.

Features

• Real-time soil moisture monitoring
• Visual representation of moisture data over time (last 100 readings)
• Responsive web interface for viewing data
• Automatic data logging every 3 hours
• Self-hosted on a linux-based VPS with automatic restarts using PM2

Planned Features

• Notifications for low moisture levels
• Integration with other sensors (e.g., temperature, humidity)
• Enhanced data visualization (e.g., historical data analysis)
• Sqlite for long-term data storage

Installation & Setup

Prerequisites

• Node.js and npm installed
• ESP32 microcontrollers and soil moisture sensors

Steps

Server

1. Clone the repository:

   git clone https://github.com/yourusername/plant-watch.git
   cd plant-watch

2. Install dependencies:

   npm install

3. Delete API related code

4. Start the application:

   npm start

5. Access the application at http://localhost:3000.

Esp32

1. Connected the ESP32 to a power source via the VIN and GND pins. Connect the moisture sensor via the GPIO15, GND, and GPIO36 pins.

2. Using the Ardruino IDE, verify and upload the code in esp32.ino to your Esp32.

• Replace the ssid and password with your local network, and change the serverName to localhost:3000/data.
• Change the plant name to your own.

Usage

• Access the web interface at http://localhost:3000 to view live moisture data.
• The chart displays the last 100 moisture readings, updated every 3 hours.
• Future features will include notifications for when moisture levels fall below a certain threshold.
