Smart 4-in-1 Air Quality Sensor

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

• ✅ HCHO (Formaldehyde)

• ✅ VOC (Volatile Organic Compounds)

• ✅ Temperature

• ✅ Humidity

▶️ 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 thresholds are exceeded.

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

▶️ 2.4GHz WIFI CONNECTIVITY

• Easy Installation: Simply connect to power and pair with your home WiFi network in minutes.

• Convenience: No need to purchase additional ZigBee hubs or gateways.

▶️ 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 charts in the application.

▶️ Example Smart Home Scenarios

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

▶️ Advantages of the WiFi Version

• Direct Connection: The sensor connects to the cloud directly through your home router.
• Quick Start: Ideal for those starting their Smart Home journey – requires no ZigBee infrastructure planning.
• Accessibility: Full functionality and remote access from anywhere in the world via the internet.
