AirGuard TH
SKU:SNZB-02DR2
Manufacturer:SONOFF
New
The SONOFF AirGuard TH (SNZB-02DR2) is a Zigbee 3.0 smart temperature and humidity sensor designed for precise indoor climate monitoring, featuring a large 3.6-inch LCD display for clear data visibility. It provides a comprehensive overview of environmental conditions by displaying current readings alongside daily maximum and minimum values.
Key Features
- High-precision sensing with accuracy ratings of ±0.2°C for temperature and ±2% RH for humidity.
- Remote T&H Display function allows the screen to show data from other SONOFF sensors within the same Zigbee network for multi-room monitoring.
- Dual-mode connectivity supports Zigbee 3.0 for smart home integration via a gateway and Proximity mode for direct Bluetooth connection to a smartphone.
- Advanced analytics via the eWeLink app, including dew point calculation, Vapor Pressure Deficit (VPD) data, and 6 months of historical data storage.
Applications
This device is ideal for centralized climate management, allowing users to monitor conditions in different rooms or outdoor areas without a smartphone. Its high accuracy and specialized metrics like VPD make it particularly suitable for sensitive environments such as greenhouses, wine cellars, or nurseries.
