GreenBlue Outdoor WiFi Temperature and Humidity Sensor, Android/iOS, 3.0V DC, LR03x2, IP65, GB741

Smart outdoor temperature and humidity sensor

WIFI TEMPERATURE AND HUMIDITY SENSOR FOR INDOOR AND OUTDOOR USE
Keep a constant eye on conditions in your home, garden, greenhouse, garage, gazebo, or utility room with the GreenBlue GB741 WiFi temperature and humidity sensor, rated IP65. The device allows you to conveniently monitor the microclimate in a selected location and react quickly when the temperature or humidity level exceeds the set values. Thanks to its durable design, the sensor is suitable not only for indoor use but also for areas exposed to dust, moisture, or splashes.
REAL-TIME CONDITIONS IN THE APP
The sensor works with popular apps like Tuya Smart and Smart Life, 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 throughout the day. This is a practical solution for monitoring conditions both indoors and outdoors—on a terrace, in a greenhouse, garage, gazebo, winter garden, or backyard shed.
IP65 RATING — OUTDOOR INSTALLATION CAPABILITY
The IP65 rating expands the sensor’s range of applications and allows it to be used in places where standard indoor devices might not perform adequately. The housing provides protection against dust and water falling on the device at various angles, so the sensor can be installed outdoors, for example under a canopy, on a facade, in a gazebo, greenhouse, garage, or utility room. This is a good choice if you want to monitor temperature and humidity not only inside your home but also in the building’s surroundings.

CALIBRATION OPTION
The GB741 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 environmental control and allows you to better adapt the device’s operation to the specific installation location. The calibration feature is particularly useful wherever you want to monitor the microclimate more effectively—in a greenhouse, sunroom, pantry, garage, child’s room, office, or electronics room.
NOTIFICATIONS THAT HELP YOU RESPOND IN TIME
One of the greatest advantages of the GB741 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 selected location has become too cold, too hot, too dry, or too humid. This is particularly useful when monitoring conditions in a greenhouse, garage, gazebo, basement, storage shed, utility room, or in places where plants, tools, supplies, or moisture-sensitive equipment are stored.
AUTOMATION WITH TUYA SMART AND SMART LIFE
The GB741 sensor can become an important part of your smart home and garden. 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, dehumidifier, fan, heater, air conditioner, or other device to turn on automatically when a specific temperature or humidity level is reached. This allows your smart home system to respond to changing conditions without the need to manually check readings.
