GreenBlue Outdoor WiFi Temperature and Humidity Sensor, Android/iOS, 3.0V DC, LR03x2, IP65, GB741, 2 pieces

External temperature and humidity sensors (2 pcs.)

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 Wi-Fi temperature and humidity sensor, featuring an IP65 rating. The device lets you conveniently monitor the microclimate in a selected location and respond quickly when the temperature or humidity level exceeds the set thresholds. Thanks to its durable design, the sensor works well not only indoors but also in areas exposed to dust, moisture, or splashes.
REAL-TIME CONDITION MONITORING IN THE APP
The sensor is compatible with the popular Tuya Smart and Smart Life apps, allowing you to check 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 throughout the day. This is a practical solution for monitoring conditions both indoors and outdoors—on a patio, in a greenhouse, garage, gazebo, sunroom, or backyard shed.
IP65 RATING — SUITABLE FOR OUTDOOR INSTALLATION
The IP65 rating expands the sensor’s range of applications and allows it to be used in places where standard indoor devices might not be sufficient. 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 building facade, in a gazebo, greenhouse, garage, or utility room. It’s a good choice if you want to monitor temperature and humidity not only inside your home but also in the area surrounding the building.

ABILITY TO CALIBRATE READINGS
The GB741 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 increases the precision of environmental 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 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 Wi-Fi temperature and humidity sensor is the ability to set your own alarm thresholds. When readings exceed the level you’ve set, 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 especially useful for monitoring conditions in a greenhouse, garage, gazebo, basement, storage shed, utility room, or any place 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.
