sensor. The acceleration of gravity is obtained through linear fitting by measuring the relationship between relative
altitude and air pressure. This new method needs not additional equipment and the experimental procedure is
easy to do.
Key words: smartphone; pressure sensor; temperature sensor; acceleration of gravity
