The H3 Human Presence Sensor uses millimeter-wave radar technology to accurately detect human movement, standing, and even static presence.
Detects Subtle Human Movements
It can detect subtle human movements such as breathing and micro-motions, significantly improving presence detection accuracy.
2.4GHz mmWave radar detects motionless people – lights stay on
Filters curtains, A/C, small pets to prevent false triggers
Adjustable 0‑255lux threshold – no light when bright, saves energy
Bluetooth setup: detection range, delay time, energy threshold
