-| **ESP32**                | 32-bit microcontroller, Wi-Fi & Bluetooth enabled    | Acts as the central controller for system operations. |
-| **PIR Sensor (HC-SR501)**| Motion detection, adjustable sensitivity and delay   | Detects motion to activate/deactivate the lighting system. |
-| **LDR Sensor (KY018)**   | Photoresistor module, light-dependent resistor       | Measures ambient light levels for adaptive brightness control. |
-| **IR Sensor (TCRT5000)** | Infrared emitter and detector for proximity sensing  | Provides additional motion detection capabilities.    |
-| **Relay Module (Songle SRD-05VDC-SL-C)** | 5V 2-channel relay module, max output 250V AC or 30V DC | Controls the LED bulb by switching it on/off.        |
-| **5V/3.3V Power Adapter**| Standard USB 5V/2A power supply                     | Supplies stable power to the ESP32 and other components. |
-| **Voltage Regulator (LM1117 3.3V)** | 3.3V linear voltage regulator             | Converts 5V input to 3.3V for components requiring lower voltage. |
-| **Jumper Wires/Breadboard** | Assorted male-to-male and male-to-female wires    | Used for temporary circuit connections during testing. |
-| **LED Bulb**             | LED bulb compatible with relay switching            | Serves as the primary light source controlled by the system. |
