Key Features & Benefits
- At-a-Glance Readings on a Large LCD Display
Instantly see the real-time temperature and humidity on the clear 2.5-inch screen. With large, bold numbers and intuitive icons for air conditions (Hot/Cold/Dry/Wet) and battery status, you'll always know your room's comfort level in a single second.
- High-Accuracy Swiss Sensor & 5s Fast Refresh
A great price doesn't mean sacrificing quality. At the heart of this sensor is a high-precision, Swiss-made hygrometer that provides lab-grade accuracy of up to ±0.2°C (±0.4°F) and ±2%RH. With data refreshing every 5 seconds, you get the most current readings for truly reliable smart home automation.
- Remote Monitoring & Instant App Alerts
Stay connected to your home's climate from anywhere. Monitor real-time data on your phone with a reliable connection up to 120m / 400ft. If the temperature or humidity ever goes outside your comfort zone, you'll receive an instant alert on the app.
- Free Data Storage & Export Included
Analyze trends and understand your environment better. Enjoy up to a half-year of free cloud data storage, viewable in clear graphs by the hour, day, or month. You can even export your data history as a .CSV file for your records.
Unlock Full Smart Home Potential
The SNZB-02D is more than just a monitor; it's a trigger for a smarter home. Set the temperature or humidity to control other devices automatically. For example, turn on a humidifier when humidity drops below 40%, or activate a fan when the room gets too warm. It works seamlessly with Alexa and Google Home—just ask to get an instant temperature or humidity update.
Place It Anywhere: 3 Flexible Mounting Options
Designed to fit perfectly into any space, the SNZB-02D can be placed wherever you need it most. Ideal for your living room, baby room, kitchen, greenhouse, guitar room, reptile terrarium, humidor, wine cellar, or incubator.
