LD2410C Zone Detection with OLED Display and WLED Control

This project utilizes the LD2410C radar sensor for zone-based presence detection and integrates it with WLED for lighting control. The system monitors movements and presence within defined zones, displays real-time status on an OLED screen, and dynamically controls WLED lighting based on detected activity.

Features:

• Presence Detection: Detects both stationary and moving targets using the LD2410C radar sensor.
• OLED Display: Displays zone status, target presence, and distance measurements.
• WLED Integration: Automatically turns WLED lighting on/off based on radar data.
• EEPROM Storage: Saves zone number and WLED IP address for persistence across device restarts.
• Wi-Fi Configuration: WiFiManager is used for easy Wi-Fi and device setup through a configuration portal.
• Customizable Zones: Dynamically adjust the number of zones to be detected.

Components:

• LD2410C Radar Sensor: For presence and motion detection.
• Carenuity_C3-Mini: The microcontroller that handles Wi-Fi, radar communication, and WLED control. ChipGlobeShop
• OLED Display (SSD1306): Displays real-time detection and zone information.
• WLED: A lighting control system controlled via Wi-Fi.

Setup:

1. Radar Setup: Connect LD2410C radar sensor to the ESP32 via specified UART pins.
2. OLED Display: Connect the SSD1306 OLED display to the I2C bus of the ESP32.
3. WLED: Configure the IP address of the WLED setup via the configuration portal.
4. Wi-Fi Configuration: Hold the reset button for 5 seconds to enter the WiFiManager portal and set Wi-Fi credentials, zone, and WLED IP.

Usage:

• The system will continuously monitor presence within the specified zones on successful setup.
• It will control the WLED brightness based on whether a person is detected within the radar’s range.
• The OLED screen provides visual feedback on the zone's status, target presence, and distance.

Applications:

• Smart Home Automation: Automatically control lighting in different rooms based on occupancy.
• Security Systems: Detect movement and control lighting in secure zones.
• Energy Efficiency: Ensure lighting is only active when someone is in the area.

Dependencies:

• WiFiManager: For easy Wi-Fi configuration.
• Adafruit SSD1306 and GFX Libraries: To drive the OLED display.
• HTTPClient: To control WLED over a local network.
