1. Weather station indoor outdoor thermometer: VA screen display is clearer with a brand design. Features a larger, clearer screen with wide viewing angles, comfortable colors, and displays indoor/outdoor temperature (°C/°F), indoor/outdoor humidity, barometric pressure, moon phase, calendar, and daily MAX/MIN data. 2. Supports up to 3 precision sensors: The temperature forecast station can connect to up to 3 remote sensors (1 included) to monitor temperature and humidity in multiple locations. Uses 433.92 RF transmission frequency with a 60meter range in open areas. 3. Measurement ranges: Indoor temperature range: 9.9°C (14.2°F) to 50°C (122°F); outdoor temperature range: 40°C (40°F) to 70°C (158°F); switchable between °C and °F. Humidity measurement range: 20%RH to 95%RH. 4. Barometric pressure trend and weather forecast: Selectable between relative and absolute air pressure. The outdoor weather station predicts weather conditions for the next 12 24 hours based on air pressure trends. Requires 7 10 days of learning and calibration when first used.
