Multi-Sensor Safety System

Overview

The Multi-Sensor Safety System is designed to monitor industrial environments for hazardous conditions. Utilizing force, pressure, and shock sensors, the system provides real-time alerts and takes preventative actions to enhance safety.

Components

1. Arduino (Microcontroller)

   • Processes input from sensors and triggers actions like alerts or shutdowns.

2. Shock Sensor

   • Detects sudden movements or machinery malfunctions.

3. Pressure Sensor

   • Monitors pressure in pipes, valves, or tanks to prevent overload.

4. Force Sensor (FSR)

   • Detects applied force to ensure safe interaction with equipment.

5. Relay Module

   • Interfaces with high-power systems for emergency shutdowns.

6. Buzzer/Alarm

   • Alerts workers audibly in case of hazards.

7. LCD/LED Display

   • Displays real-time sensor data and system status.

8. Servo Motor

   • Performs physical actions like shutting down machinery or closing valves.

9. Jumper Wires

   • Connects components to the Arduino for signal transfer.

10. USB Power Supply

    • Powers the Arduino and components for continuous operation.

Features

• Real-Time Monitoring: Continuously monitors force, pressure, and shock levels.
• Alerts:
  • Visual (LED) and audible (buzzer) alerts for hazards.
  • Logs hazard details to the Serial Monitor.
• Automated Responses:
  • Activates the servo motor to perform safety actions.
• Customizable Thresholds: Configure FSR_THRESHOLD and PRESSURE_THRESHOLD to adapt to specific use cases.

Testing and Adjustments

1. Threshold Calibration

   • Adjust FSR_THRESHOLD and PRESSURE_THRESHOLD by observing sensor outputs in the Serial Monitor.

2. System Validation

   • Simulate hazards to test alert mechanisms and servo motor responses.
