Tuya ZG-205 Smart Presence Sensor

MmWave Radar Technology Accurate Presence Detection

Tuya ZG-205 is a smart presence sensor that uses advanced 5.8GHz millimeter wave (MmWave) radar technology, allowing for more accurate human presence detection than traditional PIR motion sensors.

The device is capable of detecting even very small movements such as:

• Hand movements.

• Head movements.

• Works while sitting at work.

• Person resting or reading a book.

Thanks to that, the system can accurately determine whether there are people in the monitoring area or not.

Real-Time Presence and Motion Detection

Unlike conventional motion sensors that only detect when there is a large movement, Tuya ZG-205 can simultaneously detect:

• Human presence.

• Large movements.

• Small movement.

• Status of presence or absence of people in the area.

This helps prevent lights or devices from automatically turning off when the user is still sitting in the room.

High Performance 5.8GHz Radar Technology

MmWave 5.8GHz radar allows the device to operate stably with high accuracy in many different environments.

Advantages of this technology include:

• High sensitivity.

• Quick response.

• Continuous detection capability.

• Works stably in low light conditions or at night.

• Does not depend on body temperature like PIR sensors.

Thanks to that, the device always maintains accurate identification at all times.

Supports Small Motion Detection

One of the outstanding advantages of Tuya ZG-205 is the ability to detect micro motion.

Recognizable devices:

• Keyboard typing.

• Turn the page of the book.

• Hand movements.

• Change sitting position.

• Slight movement in the workspace.

This is an especially important feature in offices, classrooms, meeting rooms or bedrooms.

Ability to Operate Through Glass

Using millimeter wave radar technology, Tuya ZG-205 can detect presence through glass surfaces or thin non-metallic materials.

This makes installation more flexible in many spaces such as:

• Glass office.

• Meeting room.

• Display area.

• Automatic glass door.

• Modern houses use many glass walls.

Create Automatic Smart Home Scenarios

Tuya ZG-205 presence sensor can be combined with other devices in the Tuya Smart ecosystem to build automation scenarios.

For example:

• Someone enters the room → The light turns on automatically.

• No one in the room → Turn off the light after the set time.

• Presence detected → Air conditioning activated.

• There are people in the meeting room → The lighting system and projection equipment automatically operate.

• No one → Switch to power saving mode.

These scenarios help improve comfort and reduce power consumption.

Connecting Tuya Smart Ecosystem

Tuya ZG-205 works in sync with Tuya Smart and Smart Life platforms, allowing users to:

• Monitor sensor status in real time.

• Creates an automation context.

• Remote device management.

• Combine with other Tuya sensors and devices.

The entire system is managed on a single application, making operations simpler and more efficient.

Compact and Modern Design

The sensor is compactly designed, suitable for installation in many locations such as:

• Ceiling.

• Wall.

• Corridor.

• Office.

• Living room.

• Bedroom.

• Meeting room.

Modern design helps the device easily blend with any interior style.

Practical Application

Tuya ZG-205 is suitable for many usage environments:

• Smart home.

• Apartment.

• Villa.

• Office.

• Meeting room.
