Description

The Moresense MS58-2020D85U4 utilizes the Doppler effect, emitting high-frequency electromagnetic waves and analyzing the frequency shift of the reflected signal to detect moving objects. This principle ensures reliable operation unaffected by environmental variables such as temperature, humidity, or ambient light. The module’s mature CMOS design offers a fully integrated, high-value solution.

Featuring a built-in multi-filter algorithm, the sensor provides strong anti-interference capabilities, making it suitable for complex RF environments. Its ability to sense motion through common non-metallic barriers like glass and acrylic expands its application potential in enclosed or aesthetically sensitive installations. Factory-default parameters can be customized via serial commands or pin-level configuration for range, delay time, and operational mode.

Key Features

  • Miniaturized 5.8GHz radar module with integrated planar antenna in a 20x20mm footprint.
  • Doppler-based motion sensing with adjustable detection range (2-3M) and trigger delay time.
  • Wide-voltage power supply (3.3V to 12V DC) supported by an internal LDO regulator.
  • Dual interface support: configurable for standard UART communication or I2C protocol connectivity.
  • Selectable operational modes include normal power and ultra-low power for energy-sensitive designs.
  • Robust signal penetration through non-conductive materials like glass and acrylic panels.
  • Built-in digital filtering enhances stability against RF interference and false triggers.
  • Compliant with FCC, RED, and CE certification standards for commercial deployment.

Applications

  • Smart lighting control and presence detection for energy management in homes and offices.
  • Intrusion detection and trigger activation for wireless security cameras and smart locks.
  • Battery-powered motion sensing in solar street lights and outdoor IoT monitoring nodes.
  • Occupancy sensing through glass partitions or acrylic enclosures in retail and automated systems.
  • Human presence detection in appliances, vending machines, and touchless interfaces.

Frequently Asked Questions

What is the operating voltage range for the MS58-2020D85U4 sensor module?

The module features a built-in LDO regulator supporting a wide input voltage range from 3.3V to 12V DC. This allows for direct compatibility with common 5V microcontroller systems (Arduino, Raspberry Pi) as well as 12V industrial or battery-powered setups without requiring an external voltage regulator.

How do I communicate with and configure this radar sensor?

The module supports two configurable digital interfaces: a standard UART (serial) interface and an I2C protocol. You can send serial commands via UART to adjust parameters like sensing range, delay time, and output mode. Alternatively, the interface can be set to I2C for daisy-chaining with other sensors on the same bus.

Can this sensor detect motion through walls or windows?

Yes, the 5.8GHz microwave signal can penetrate non-metallic materials such as glass, acrylic, and thin plastic enclosures. However, it cannot detect motion through metal barriers or conductive materials, which will block the signal. This makes it ideal for sensing occupancy behind glass panels or inside covered fixtures.

What is the difference between the normal and ultra-low power modes?

In normal power mode, the sensor operates with continuous or frequent scanning for immediate response. Ultra-low power mode periodically puts the radar IC into a deep sleep state, significantly reducing average current consumption for battery-powered applications like solar lights or wireless sensors, with a trade-off in wake-up latency.
