rain indicator - a meterological

a meterological LED Table Prediction accuracy during the test period: England 80% Scotland 89% Wales 87% N. Ireland 91% Irish Republic 93% Netherlands 85% Germany 78% France 71% next twenty-four hours. If the LED is not lit it is wise to remember your raincoat and umbrella. The table given here shows just how accurate the circuit"s predictions were during the test period last winter. A vari- ation on this theme is to use a bat- tery with a slightly higher voltage. The circuit must then be built in summer and the intensity of the LED"s light indicates the probability of accuracy of the prediction. In spite of all their sophisticated weather-predicting equipment, meterological services around the I world have a reputation for not 0 always getting it right (to put it T mildly!). Because of this many people try to predict the weather themselves as much as possible. They vigilantly tap the barometer every morning and then rack their brains to remember whether high pressure means good W...
