Frequently Asked Questions About mmWave Sensors

Q1: Are mmWave sensors suitable for outdoor applications?

Yes, mmWave (millimeter-wave) sensors are highly suitable for outdoor environments—especially when equipped with ruggedized housings and protective ratings such as IP67 or higher. These sensors are inherently resistant to challenging environmental factors including moisture, dust, fog, rain, snow, and extreme temperature fluctuations, making them ideal for reliable performance in harsh outdoor conditions.

Unlike optical or infrared sensors, mmWave sensors operate using radio frequencies (typically in the 24 GHz, 60 GHz, or 77 GHz bands), which are less affected by poor visibility or adverse weather. This makes them a preferred choice for applications such as outdoor security systems, traffic monitoring, smart lighting control, and perimeter surveillance.

Q2: How do millimeter-wave sensors work in areas with obstacles?

Millimeter-wave sensors can still function effectively in partially obstructed environments, though their performance may vary depending on the material and density of the obstacle. The radar signals used by mmWave sensors can penetrate certain non-metallic materials like plastic, wood, drywall, and glass, allowing for detection through barriers under specific conditions.

However, optimal performance requires a clear line of sight between the sensor and the target. Metallic objects, thick concrete walls, or water-filled materials tend to reflect or absorb mmWave signals, which can reduce detection accuracy or range. While basic functions like motion detection and distance measurement can persist in obstructed setups, precision in speed, position, and gesture recognition improves significantly with unobstructed signal paths.

For best results, install mmWave sensors with minimal physical interference and consider the dielectric properties of surrounding materials during system design.
