The highly accurate sensors of the Seal measure the weather conditions such as actual pressure, development of pressure during the day and temperature and can therefore give a good indicative forecast of the weather.
The high quality solar panel is integrated in the base of the Seal and becomes a natural part of the beautiful design of the product.
The solar panel charges the internal Ni-MH batteries, so even without sunlight the Seal can make its measurements and display the information.
For periods of no sunlight over a long time, the Seal has the option of a back-up battery.
