Multi-function lamp controller based on ESP32-C3

Project Description:
This project, based on the ESP32-C3, creates a multi-functional control module for lighting. It can be connected to Home Assistant to achieve various automated controls. The project integrates an LD2410 human presence sensor, a temperature and humidity sensor, touch sensing, and offline voice functionality.
Schematic Design:
Power Supply:
220V; Lights
: SSD1306; Display: Control
Sensors :
Temperature and Humidity Sensor;
Touch Sensing and Human Presence Sensor;
Offline Voice Function: Main
Control Chip:
ESP32-C3;
PCB Design:
The temperature and humidity sensor is placed separately on the outside of the casing to prevent heat-generating components from affecting the temperature.
The software part
uses esphome to program c3 and access the homeassistant
