How to judge the weather based on the air pressure on your watch

Casio PROTREK has a triple sensor function, which can measure orientation, air pressure/temperature and altitude. Especially the third generation triple sensor, compared with the previous generation, the volume has been reduced by 95% and the energy consumption has been reduced. 90%, so the overall dial is relatively thin and compact, which is very suitable for both men and women. To judge the weather from the barometric pressure map, you only need to operate one button, and the LCD screen can display the changes in air pressure. If the pressure curve shows a downward trend, it means that low pressure is approaching and heavy rain may occur; if it shows an upward trend, it means that the weather is improving. Weather forecasts can help climbers plan their descent routes in advance.
