Board 2: Energy Management and Environmental Monitoring

This board focuses on energy efficiency and environmental monitoring within the Radiance Smart City project. It manages street lighting based on ambient light conditions, allows manual control via remote, remote functions, and monitors fire and flood situations.

Connections

• IR Receiver: Connected to pins 6.

• LDR (Light Dependent Resistor): Connected to pin A0.

• Water Level Sensor: Connected to pin A1.

• Street Light LEDs: Connected to pin SLledPin (8).

• Residential Blocks Light LEDs: Connected to pins: block1LEDPin (A2), block2LEDPin (A3), block3LEDPin (A4), block4LEDPin (A5).

• Gate Control Pin (to Board 1 - Remote Signal Pin): Connected to pin controlgate (4).

• Gate Lockdown Pin (to Board 1 - Remote Lockdown Pin): Connected to pin gateLockdownPin (5).

• Alarm System, LEDs and Buzzer:

  • Fire Alarm:

    • Fire Sensor: Connected to pin flameInPin (7).
    • Fire Red LED: Connected to pin fireRedLedPin (13). Indicates fire detection.
    • Fire Green LED: Connected to pin fireGreenLedPin (12). Indicates no fire.
    • Fire Signal Out (to Board 3 - Fire Signal In): Connected to pin fireOutPin (10).

  • Water Alarm:

    • Water Level Sensor: Connected to pin waterInPin (A1).
    • Water Red LED: Connected to pin waterRedLedPin (3). Indicates rising water levels.
    • Water Green LED: Connected to pin waterGreenLedPin (2). Indicates safe water levels.
    • Flood Signal Out (to Board 3 - Flood Signal In): Connected to pin waterOutPin (9).

  • Buzzer: Connected to pin alarmBuzzerPin (11).

• NB: all negative (-ve/GND) wires are connected to GND.

For detailed connections, refer to the Circuit Diagram.

LDR (Light Dependent Resistor) Mode and Remote Control

• LDR Mode: The street lights are controlled based on ambient light conditions using the LDR sensor. Adjust the LDR_LOW_LIMIT value to fine-tune the sensitivity of the LDR to achieve optimal performance in various lighting environments.

• Remote Control: Aside the gate operation, the IR remote allows manual control of street lights and residential blocks lights.

  • Street light control: When the switch mode button is pressed, it switches the mode from automatic mode to manual mode. In the manual mode, a pressed power button turns the light on/off. The switch mode button needs to be pressed to switch the mode back to automatic mode.
  • Residential blocks light control: When the appropriate button is pressed, it triggers the various block LED pin. This turns the respective lights on/off.

Fire and Water Alarm System Operation

• Fire Alarm System: The fire sensor constantly monitor the environment for potential fire incidents.

• Water Alarm System: The water level sensor actively gauges water levels.

• Both systems, integrates visual indicators to signal detection, ensuring a visual distinction. In conjunction with the visual indicators, an alarm is employed to provide an audible alert during critical situations.

Usage

1. Adjust configurations in the code if necessary.
2. Upload the Board2_EnergyEmergency.ino code to your Arduino board.
3. Connect the components as specified in the connections section.
4. Power on the system and test the LDR-based street light control, remote functions and fire/water alarm systems.

Refer to the code file for detailed comments and configuration instructions.
