Multi-function lamp controller based on ESP32-C3

This project, based on the ESP32-C3, developed a multi-functional control module for lighting control. It can be connected to Home Assistant to achieve various automated control functions. The project integrates an LD2410 human presence sensor, temperature and humidity sensors, touch sensing, and offline voice functionality.

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
