Govee Digital Thermometer and Temperature and Humidity High Large Graph Error Maximum and Minimum Temperature and Dryness Humidification Indoor

High-Precision Sensor: The built-in Swiss-made SHT30 sensor provides highly accurate and reliable temperature and humidity measurements with a maximum temperature error of ±0.3°C and humidity error of ±3% RH. This digital thermometer/hygrometer updates data every two seconds, providing excellent accuracy and sensitivity. (Note: This product is not waterproof. The operating temperature range is -20°C to 60°C. Do not use in humid environments, inside a refrigerator, or outdoors in the rain.) Temperature and Humidity Alert Notification Function: If the temperature and humidity ranges set in the app are exceeded, you will receive an alert notification from the app within Bluetooth communication range. This is useful as a preventative measure against dryness and heatstroke, and is recommended not only for homes with elderly people or babies, but also for homes with pets (dogs, cats, rabbits, reptiles, etc.). Bluetooth Connection and Remote Monitoring: The Govee Bluetooth thermometer and hygrometer allows you to remotely monitor temperature and humidity up to 50 meters using the Govee Home app. There's no need to be close to the thermometer; you can easily read temperature and humidity information on your smartphone. It's also useful for preventing heatstroke, dryness, and influenza. (Bluetooth connection distance is limited to 50 meters.) Compact LCD Screen: The LCD screen displays real-time temperature and humidity readings, as well as maximum and minimum readings. It also displays three levels of comfort, allowing you to easily understand the room's temperature, humidity, and comfort level. This is useful for preventing heatstroke and for monitoring the health of your family, including the elderly and babies. [Historical Data Recording/Export] The app stores data from the past 60 days. Temperature and humidity are visualized in graphs, and you can check historical data for specific times in the app. You can also export data (CSV files) to check changes in your home's temperature and humidity. The battery life of this thermo-hygrometer is 12 months. Please replace it in a timely manner. A low battery may cause abnormal display and inaccurate temperature and humidity readings.
