SONOFF ZigBee SNZB-02DR2 Temperature and Humidity Sensor 2-Pack

The Sonoff AirGuard TH SNZB-02DR2 is a smart ZigBee temperature and humidity sensor with a large 3.6” LCD display that shows current conditions, daily highs and lows, and air comfort levels in real time. It combines laboratory-grade precision (±0.2°C / ±2% RH), modern wireless connectivity, and energy-efficient battery operation in a single, compact device. With it, you always know whether the room has a healthy microclimate—no guessing, no assumptions, no unnecessary complications.

Clear and large 3.6” LCD screen

The clear, high-contrast display is designed so that the most important data is visible from a distance. A single glance is all it takes to check the temperature, humidity, min/max values from the last 24 hours, and the graphical comfort indicator. You don’t have to open an app or reach for your phone—the information is always at your fingertips, exactly when you need it.

Precise, premium-class sensor—Sensirion SHT40

At the heart of the device is the professional Sensirion SHT40 sensor, known for its use in industrial and measurement applications. It provides exceptionally stable and reliable readings, which translate into real benefits: better sleep conditions, healthier air for children, and protection for plants, food, and wine against excessive moisture. This is a device that measures accurately—because when it comes to comfort, there’s no room for chance.

ZigBee 3.0 – Smart, Wireless Automation

Thanks to ZigBee 3.0 connectivity, the sensor operates reliably, responds quickly, and consumes minimal energy. Once paired with the gateway, you can monitor data in the app, set alerts, and create automations—such as turning on a humidifier when the air is too dry or activating ventilation when humidity is too high. It’s a smart home that takes care of your comfort on its own before you even notice a problem.

Data History and Analytics

AirGuard TH records measurements and displays them as easy-to-read graphs, allowing you to track changes over time—with accuracy down to the minute. Daily, weekly, and multi-month statistics are available, as well as information on dew point and VPD. It’s a practical tool that helps you better plan ventilation, heating, and plant watering, and effectively prevent mold and excessive moisture.

Works with your smart home system

The sensor integrates seamlessly with popular platforms and hubs: Sonoff, Home Assistant, Zigbee2MQTT, SmartThings, as well as voice assistants like Alexa and Google Home, and the Matter Bridge ecosystem. You can check the temperature using voice commands, view data remotely, and turn devices on from anywhere. This gives you complete freedom and flexibility, regardless of your chosen ecosystem.

Proximity Mode—use it even without a gateway

Don’t have a ZigBee hub? No problem. In Proximity Mode, you can connect directly to your smartphone via Bluetooth to check current parameters, calibrate the sensor, switch between °C and °F, or export data. It’s the perfect solution for those who want to start with simple monitoring and expand the system with automation later.

Compact design and versatile use

A slim housing made of durable PC+ABS, powered by two AAA batteries, and the option to stand it upright or hang it mean that the AirGuard TH fits literally anywhere—in a bedroom, a child’s room, a greenhouse, a pantry, a basement, a storage room, or an office. A wide operating range (-20°C to 60°C, 5–95% RH) ensures reliability in various conditions. This small device gives you great control over the comfort and safety of your environment every day.
