The Tuya Zigbee 10G mmWave radar sensor is designed for smart home systems to detect human presence. Unlike passive infrared (PIR) sensors that only detect motion, mmWave radar can sense subtle movements like breathing, allowing it to determine if a person is present even when they are still. This makes it suitable for applications where continuous occupancy detection is needed, such as turning lights off only when a room is truly empty.
How mmWave radar detects presence
MmWave (millimeter wave) radar technology operates by emitting high-frequency radio waves and analyzing the reflections. The listing describes this as a "10G MmWave Radar" sensor, indicating its operating frequency. By detecting minute changes in these reflections, such as those caused by a person's breathing or heartbeat, the sensor can maintain an 'occupied' status even when the person is stationary. This capability differentiates it from traditional motion sensors that would register a room as empty once movement ceases.

Before you order
- What is mmWave radar?
- MmWave radar detects subtle movements, including breathing, allowing it to sense human presence even when a person is still. This differs from traditional motion sensors that only detect active movement.
- Do I need a hub for this sensor?
- Yes, a Tuya-compatible Zigbee hub is required. The sensor communicates using the Zigbee protocol and cannot connect directly to a Wi-Fi network.
- Can this sensor detect pets?
- The listing describes it as a "human body sensor," implying it is tuned for human presence. The listing does not provide details on its ability to distinguish between humans and pets or its sensitivity to animal movement.
