Plant Factory in Arduino

This project is a smart home system that uses various sensors and actuators to monitor and control the environment. The system includes an ultrasonic sensor, a DHT11 temperature and humidity sensor, a moisture sensor, a light sensor, a servo motor, a buzzer, an LED strip, and a relay.

Components

• Ultrasonic Sensor (HC-SR04): Measures distance to detect obstacles.
• DHT11 Sensor: Measures temperature and humidity.
• Moisture Sensor: Measures soil moisture level.
• Light Sensor: Detects ambient light levels.
• Servo Motor: Controls mechanical movement (e.g., opening/closing a window).
• Buzzer: Provides audible alerts.
• LED Strip (WS2812): Provides visual feedback.
• Relay: Controls high-power devices.

Pin Configuration

• trigPin (12): Ultrasonic sensor trigger pin
• echoPin (13): Ultrasonic sensor echo pin
• buzzerPin (6): Buzzer pin
• moistureSensorPin (3): Moisture sensor pin
• servoPin (9): Servo motor pin
• lightSensorPin (A0): Light sensor pin
• relayPin (4): Relay pin
• LED_PIN (2): LED strip data pin
• LED_COUNT (10): Number of LEDs in the strip
• DHTPIN (7): DHT11 sensor pin
• DHTTYPE (DHT11): DHT11 sensor type

Setup

1. Connect the components to the corresponding pins on the Arduino board.
2. Install the necessary libraries:
   • DHT.h
   • Servo.h
   • FastLED.h
3. Upload the code to the Arduino board.

Code Explanation

• Ultrasonic Sensor: Measures the distance to an object and triggers the buzzer if the distance is less than or equal to 4 cm.
• Light Sensor: Turns on the LED strip if the ambient light is below a certain threshold.
• DHT11 Sensor: Reads temperature and humidity values and controls the relay based on humidity levels.
• Moisture Sensor: Reads soil moisture levels and controls the servo motor to open/close a window based on the moisture level.
• LED Strip: Provides visual feedback based on the light sensor readings.

Usage

1. Power on the Arduino board.
2. The system will start monitoring the environment using the connected sensors.
3. The buzzer will sound if an object is detected within 4 cm.
4. The LED strip will turn on if the ambient light is below the threshold.
5. The relay will be activated if the humidity is below 40%.
6. The servo motor will adjust based on the soil moisture level.
