Integrated Wireless 7 in 1 in Garni 1NG Weather Station External sensor is an advanced solution for precise measurement of meteorological parameters. It is capable of monitoring outside temperature, relative humidity, wind speed and direction, rain volume, UV index and intensity of sunlight. The measured data is reliably forwarded to the main unit up to 150 meters in space. Its power supply is provided by a solar panel and a built -in capacitor that allows operation without often replacing batteries. The capacitor is located at the funnel of the rain meter and obtains energy directly from the solar panel. If you have direct sunlight with 100,000 lux intensity for four hours, it will be fully charged and will provide the sensor the energy for a full day, eliminating the use of spare batteries.
