Atmospheric pressure and trend monitoring Atmospheric pressure bar chart shows the trend over the past 3, 6, 9, 12, 18 and 24 hours. This provides a quick view of recent pressure changes to help interpret weather patterns. Includes the ability to check the trend change of level 3 air pressure for deeper analysis. Global sunrise/sunset and astronomical data Sunrise and sunset times for 251 cities around the world. You can select a city to view its times. Set the city, time zone, and latitude and longitude to display the corresponding sunrise/sunset time. The display includes 12level moon phase information and 3 level tide data for practical planning. Temperature display and trend detection Temperature display format selection is available. The system can detect the trend changes of temperature and humidity. Shows indoor and outdoor records of the maximum and minimum temperature and humidity for that day. Backlight and display usability Backlight function: when powered by battery, the backlight lights up for 15 seconds. When DC power supplies power, the backlight provides five levels of brightness ( low 4 levels, off). Night exposure mode adjusts brightness intelligently according to dim ambient light. 23 practical use scenarios Home comfort and daily planning: Monitor indoor and outdoor temperature and humidity trends, review daily max/min values, and use the pressure trend to anticipate local weather changes. The backlight behavior supports readability in varying lighting conditions, whether on battery or DC power. Outdoor activities and travel planning: Use sunrise/sunset times for scheduling early departures, and moon phase and tide data to plan coastal activities or night photography. Global city data helps when traveling to destinations without guessing local times. Coastal and marine readiness: Rely on pressure trends to assess shortterm weather shifts, tide information for planning boat or shoreline activities, and moon phase for visibility considerations, all while having easytoread backlight options for different lighting environments. Notes on compatibility and benefits The features are oriented toward comprehensive weather and environmental monitoring, with global time and astronomical data, trend analysis, and flexible backlighting to support use in various power conditions. The described functions are presented as integral capabilities of the product's weather and display system, without external accessories required for these core features.
