Sonoff AirGuard Temperature and Humidity Sensor with Display (Zigbee) (SNZB-02DR2)

The Sonoff AirGuard Temperature and Humidity Sensor (Zigbee) is a comprehensive climate monitoring hub designed for those who need high-visibility data at a glance. Boasting a large 3.6-inch LCD display, it tracks real-time temperature and humidity, 24-hour highs and lows, and even displays data from linked remote sensors (External Sonoff Sensors). Beyond basic monitoring, the eWeLink App integration provides insights.

Designed for efficiency and flexibility, the Sonoff Airguard Temperature and Humidity sensor (Zigbee). Allows users to customize reporting frequencies to save battery or ensure high-resolution data. In Zigbee mode, it can pull data from other SNZB-series sensors (02/02P/02D/etc.), allowing you to monitor multiple rooms from a single screen. So when paired with a Zigbee bridge, it serves as the perfect trigger for smart scenes, automatically activating heaters, air conditioners, or humidifiers to maintain your ideal environment.

Choosing the right AirGuard depends on which “invisible” part of your air you want to manage.

The CO2 Monitor (SAWF-08P) is best for offices and bedrooms to prevent stuffiness and headaches by tracking carbon dioxide (Breathing AQI).

The Air Quality Monitor (SAWF-07P) is essential for health if you are worried about dust, smoke, or seasonal allergies, as it detects fine floating particles (PM2.5/PM10).

The Temperature and Humidity (SNZB-02DR2) model is a specialized climate hub with a large screen, perfect for those who need to manage comfort, mold prevention, or greenhouse levels requiers a Sonoff Zigbee hub. (Temp and Humidity sensor)
