The Seeedstudio 24GHz mmWave Sensor Lite Human Presence Module w/ FMCW, Arduino Support, Home Assistant, ESP Home is an integrated antenna module that utilizes a high-sensitivity mmWave radar sensor. This sensor operates on the Frequency Modulated Continuous Wave (FMCW) principle, which enhances its sensitivity and makes it resistant to environmental interferences.

The module is designed to be user-friendly, offering visual debugging and configuration tools that simplify its operation while ensuring clear data presentation. It is highly adaptable, with a range of modifiable underlying parameters that can be adjusted to suit various scenarios. The module is compatible with the Arduino Library, utilizing UART and offering Arduino library support. Additionally, it is ready for integration with Home Assistant, with a comprehensive guide available to facilitate this process.

This radar module combines multiple functions into a single device, all of which can be customized according to specific requirements. It is capable of detecting human presence and absence, motion and direction of motion, object speed, and detected distance. It also offers an open custom function, allowing for the adjustment of parameters such as detected range, sensing sensitivity, trigger threshold, valid time for state changes, and installation environment.

The module is designed with a focus on low power output, ensuring it maintains a health-friendly operational status. Its high immunity to interferences means that the output data is less affected by environmental factors such as temperature, humidity, noise, airflow, dust, and light. The module also supports secondary development based on related upper computer software and Arduino. It can be upgraded using the over-the-air (OTA) programming method, allowing for local upgrades. With its multiple customizable functions, this radar module is an ideal motion-sensing solution, offering a range of functional configurations that can be developed to meet various application requirements.
