Tuya WiFi Temperature and Humidity Sensor, 2-Pack

WIFI TEMPERATURE AND HUMIDITY SENSOR FOR SMART HOMES
Ensure comfortable conditions in your home, apartment, office, or utility room with the practical GreenBlue GB737 Wi-Fi temperature and humidity sensor. This compact device lets you conveniently monitor the microclimate in any location and quickly respond when the temperature or humidity level deviates from your set values. It’s ideal for any space where a stable environment matters—in the bedroom, children’s room, living room, home office, greenhouse, pantry, closet, or electronics room.
REAL-TIME PREVIEW OF CONDITIONS IN THE APP
The sensor works with the popular Tuya Smart and Smart Life apps, allowing you to check the temperature and humidity directly from your smartphone. Real-time data is conveniently displayed in the app, and the ability to view measurement history makes it easy to track changes in the room throughout the day. This is especially useful when you want to monitor air quality, prevent excessive humidity or overly dry air, or maintain the right conditions for plants, pets, food, or equipment sensitive to temperature changes.

ABILITY TO CALIBRATE READINGS
The GB737 sensor offers a function for correcting temperature and humidity readings, allowing you to adjust the readings to your specific needs or calibrate them against another verified meter. This practical solution enhances the precision of indoor climate control and allows you to better tailor the device’s operation to its specific installation location. The calibration feature is particularly useful wherever you want to monitor the microclimate more closely—for example, in a child’s room, a greenhouse, a pantry, a closet, an office, or a room with electronic equipment.
NOTIFICATIONS THAT HELP YOU RESPOND IN TIME
One of the greatest advantages of the GB737 Wi-Fi temperature and humidity sensor is the ability to set your own alarm thresholds. When the readings exceed the level you’ve set, the app can send a notification to your phone. This lets you know faster if a room has become too cold, too hot, too dry, or too humid. It’s a simple solution that helps improve the safety and comfort of your daily life at home.
AUTOMATION WITH TUYA SMART AND SMART LIFE
The GB737 sensor can become an important part of your smart home. When connected to the Tuya Smart or Smart Life app, it allows you to create scenarios for the automatic operation of other compatible devices. For example, you can set a humidifier, fan, air conditioner, heater, or dehumidifier to turn on automatically when a specific temperature or humidity level is reached. This allows your home to respond to changing conditions without the need to manually check the readings.
