The C4002 is a 24GHz FMCW mmWave radar module for smart homes. It detects moving/stationary humans (10×10m range), filters interference (curtains, AC), adjusts detection range, and has configurable outputs. Compatible with Arduino, ESP32, Raspberry Pi, and Home Assistant, it speeds up R&D for smart home systems (lighting, security, etc.).
1. HomeAssistant Tutorial
This tutorial allows you to integrate the C4002 millimeter-wave sensor into HomeAssistant, and view and configure sensor data in real time.
2. Example Code for Arduino-Get All Sensor Results
This project demonstrates how to use the DFRobot_C4002 library to retrieve all detection results from the C4002 sensor, including light intensity, target state (no target, static presence, motion), presence and motion target information (distance, energy, speed, direction), etc. Users will learn how to initialize the sensor, configure its parameters, and read various detection data.
3. Example Code for Arduino-Auto Environment Calibration
This project demonstrates how to use the DFRobot_C4002 library to perform environmental calibration for the C4002 sensor. Users will learn how to initialize the sensor, configure the report period, start calibration.
