GreenBlue WiFi Temperature and Humidity Sensor, Android/iOS/Alexa/Google Home, 3.0V DC, LR03x2, GB737

Tuya Smart WiFi Temperature and Humidity Sensor

WIFI TEMPERATURE AND HUMIDITY SENSOR FOR SMART HOMES
Ensure comfortable conditions in your home, apartment, office, or utility room with the practical GreenBlue GB737 WiFi temperature and humidity sensor. This compact device lets you conveniently monitor the microclimate in a specific location and quickly respond when the temperature or humidity deviates from the set values. It works well wherever a stable environment matters—in the bedroom, children’s room, living room, home office, greenhouse, pantry, closet, or electronics room.
REAL-TIME CONDITION PREVIEW IN THE APP
The sensor works with the popular Tuya Smart and Smart Life apps, allowing you to check temperature and humidity directly from your smartphone. Current data is conveniently available in the app, and the ability to view measurement history makes it easy to observe changes occurring 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 optimal conditions for plants, pets, food, or temperature-sensitive equipment.

CALIBRATION OPTION
The GB737 sensor offers a temperature and humidity correction feature, allowing you to adjust the readings to your specific needs or calibrate them against another verified meter. This practical solution increases the precision of indoor climate control and allows you to better adapt the device’s operation to the specific installation location. The calibration feature is particularly useful where you want to monitor the microclimate more closely, such as in a child’s room, a greenhouse, a pantry, a closet, an office, or a room with electronics.
NOTIFICATIONS THAT HELP YOU RESPOND IN TIME
One of the greatest advantages of the GB737 WiFi temperature and humidity sensor is the ability to set your own alarm thresholds. When readings exceed the level you specify, 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 increase the safety and convenience of your home’s daily use.
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 readings.
