mmRat uses 60GHz millimeter-wave radar to detect small-animal and pest movement, capturing precise motion data even in complete darkness and through obstacles.
Environmental and pest-detection mmWave radar module “mmRat”
Two waveform graphs are stacked vertically to highlight the difference created by Hibiki Labs’ proprietary signal-extraction algorithms.
mmRat reliably detects subtle movements of small animals such as mice and rats hiding behind walls, beyond obstacles, or in complete darkness—areas where conventional cameras and infrared sensors struggle.
While many mmWave systems struggle with noise reduction, Hibiki Labs’ proprietary signal-extraction technology cleanly extracts accurate motion data—distance, angle, and speed—from complex environmental noise.
From commercial facilities, offices, factories, homes, and underfloor spaces, mmRat turns invisible pest-risk zones into actionable data, helping improve QoL and environmental hygiene through next-generation mmWave detection.
