Moresense MS58-2020D9M4-L 5.8GHz Microwave Radar Motion Sensor Module - 3-4m Range

The module supports a wide input voltage range from 3.3V to 12V DC. Its built-in Low Dropout Regulator (LDO) ensures stable internal operation, making it directly compatible with common 5V Arduino boards and 3.3V logic systems like ESP32 or Raspberry Pi without requiring an additional voltage regulator.

Sensitivity (range) and the output signal hold time are configurable via the module's reserved I/O pins. You can connect these pins to external resistors or control them directly with a microcontroller's GPIO to set the parameters according to your specific application requirements, such as the size of the area to monitor.

No, it cannot penetrate conductive materials like metal. However, it is effective at detecting motion through non-metallic, low-density materials such as glass, acrylic, plastic, and thin wood. This makes it suitable for concealed installation inside lighting fixtures, behind decorative panels, or within electronic enclosures.

The module provides a direct digital control signal from its integrated System-on-Chip (SoC). The output pin typically switches from a high to a low logic state (or vice-versa) upon motion detection. You can connect this output pin directly to a digital input pin on an Arduino or other microcontroller to read the state change and trigger your code.

No. As a microwave radar sensor, its operation is based on the Doppler frequency shift of reflected radio waves, making it inherently immune to common environmental variables. It will not be falsely triggered by changes in ambient light, temperature, humidity, airflow, dust, or audible noise, ensuring reliable performance in diverse conditions.
