Seeed Studio Studio 24GHz mmWave Sensor - Human Static Presence Module Lite - FMCW Radar, Configurable Parameters, Arduino & Home Assistant Support

The module requires a regulated DC power supply between 4.5V and 5.0V. Exceeding this range may damage the internal RF components. Typical operating current is between 95 mA and 120 mA.

The sensor uses a UART serial interface at a fixed 115200 baud rate. You can send configuration commands and read detection data via TX/RX pins. Seeed Studio Studio provides an Arduino library and visual configuration tools to simplify parameter adjustment for range, sensitivity, and trigger conditions.

The default static presence detection range is approximately 3 to 3.5 meters. This range is configurable via serial commands, allowing you to reduce it for smaller rooms or increase sensitivity for specific applications, though maximum reliable range is limited by the 6-8 dBm output power and environment.

As an RF-based sensor, it can detect movement through thin, non-metallic materials like drywall, wood, or plastic. However, metallic objects and thick, dense materials will block the 24GHz signal. It is designed for line-of-sight or semi-obstructed indoor applications like ceiling-mounted occupancy sensing.

Yes. The UART interface makes it directly compatible with any microcontroller with a serial port, including ESP32, ESP8266, and Raspberry Pi. Official integration guides are provided for ESPHome and Home Assistant, allowing you to add presence detection as a native entity in your home automation dashboard.
