🍷 Bacchus Sense (Light Monitoring System for Wine Storage)

📌 Project Description

Named in honor of Bacchus, the Roman deity of wine, Bacchus Sense blends classical inspiration with modern monitoring technology.

This project consists of an intelligent light monitoring system for wine storage environments, using Arduino, an LDR sensor, indicator LEDs, and an alert buzzer.

Excessive light exposure can compromise the quality, flavor, and preservation of wine, especially in locations such as:

• Residential wine cellars
• Wineries
• Commercial inventories
• Climate-controlled warehouses
• Logistics storage environments

The system continuously monitors the ambient light levels and alerts when they exceed safe limits.

---

🎯 Objective

Develop an embedded system capable of:

• Monitoring ambient light levels
• Classifying light intensity in real-time
• Alerting when there is inadequate exposure
• Assisting in the preservation of the quality of stored wines

---

⚙️ How the System Works

The LDR sensor reads the ambient light, and the Arduino interprets the received values.

Based on these values:

Light Intensity	LED	Status	Buzzer
High (> 600)	🔴 Red	Preservation Risk	Activated
Medium (400 – 599)	🟡 Yellow	Attention	Deactivated
Low (< 400)	🟢 Green	Ideal	Deactivated

When the environment presents high luminosity, the system triggers a sound alert to indicate inadequate storage conditions.

🧠 Importance of Lighting Control

Prolonged exposure to light can cause:

• Premature oxidation
• Alteration of aroma
• Alteration of flavor
• Beverage degradation
• Reduction of the wine's shelf life

Therefore, constant monitoring is essential in storage environments.

💻 System Logic

The system continuously executes:

1. Ambient light reading
2. Sending values to the Serial Monitor
3. Light level classification
4. Automatic activation of indicator LEDs
5. Buzzer activation in critical conditions

Allowing for simple and efficient real-time monitoring.
