Human Presence Motion Sensor with 16A Relay & Luminance Detection

Product Description

Upgrade your smart home automation with this advanced mmWave radar human presence sensor, designed for high-accuracy motion, micro-movement, and static presence detection. Unlike traditional PIR sensors, this device can detect people even when they are sitting, sleeping, or barely moving, making it ideal for lighting automation, energy saving, and security applications.

The sensor supports  WiFi connectivity, features a built-in 16A relay, and includes illuminance (lux) detection for intelligent scene automation.

Perfect for homes, offices, corridors, bathrooms, bedrooms, and smart buildings.

Key Features

✅ Advanced mmWave Human Presence Detection

Detects:

• Human presence

• Human movement

• Micro-motion

• Static presence (sleeping or sitting still)

Uses millimeter-wave radar technology, ensuring reliable detection even when there is no visible movement.

✅ Built-in 16A Relay (Optional Use)

Control lights or appliances directly without an extra smart switch.

Relay Modes:

• Cloud Control Mode – Remote ON/OFF via app

• Local Automatic Mode – Turns ON when presence is detected, OFF when area is empty

• Relay Disabled Mode – Sensor only, no load control

Supports loads up to:

• 3000W (resistive)

• 300W (LED)

✅ Smart Illuminance (Lux) Detection

• Built-in 0–500 Lux brightness sensor

• Adjustable illuminance threshold (0–420 Lux)

• Automate lighting based on both presence and ambient light

• Prevents lights from turning on during daylight

Perfect for energy-efficient automation
