Smart 4-in-1 Air Quality Sensor

ZigBee | Tuya / Smart Life | Android / iOS | Micro-USB DC 5V

• ✅ HCHO (Formaldehyde)

• ✅ VOC (Volatile Organic Compounds)

• ✅ Temperature

• ✅ Humidity

⚠️ Device requires a ZigBee Gateway

▶️ AIR MONITORING

• 4-in-1 Measurement: HCHO (formaldehyde), VOC (organic compounds), Temperature, Humidity.

• Precision: High-sensitivity electrochemical sensor for pollutant detection.

▶️ SMART AUTOMATION

• Scenarios: Automatically trigger devices (e.g., air purifier) when air quality limits are exceeded.

• Remote Access: Real-time monitoring on your Smartphone via Tuya or Smart Life apps.

▶️ ZIGBEE 3.0 CONNECTIVITY

• Reliability: Stable communication without overloading your home Wi-Fi network.

• Speed: Automation response time as fast as 0.2 seconds.

▶️ Why is it important?

• Volatile Organic Compounds (VOC): Toxic substances evaporating from paints, varnishes, new furniture, or cleaning agents.

• Formaldehyde (HCHO): A colorless, irritating gas present in many building and finishing materials.

▶️ Comfort and Health

• Climate Optimization: Thanks to the built-in thermometer and hygrometer, you can ensure proper humidity and temperature in the room.

• Data History: Track air quality changes over time with clear graphs in the app.

▶️ Example Smart Home Scenarios

1. Chemical Detection: If VOC levels exceed the limit -> Tuya activates the air purifier or heat recovery system.
2. Too Dry: If humidity drops below the set threshold -> a smart plug turns on the humidifier.
3. Heating Control: If the temperature falls below the comfort level -> the system starts the heating.

▶️ Advantages of ZigBee 3.0 Protocol

• MESH Network: Stable connection even in large buildings by relaying signals between devices.

• Security: Encrypted data transmission and high resistance to interference.

• Scalability: Connect dozens of sensors without slowing down your Wi-Fi router's performance.
