Abstract

One experiment is designed by using the sensors in smartphone including pressure sensor，temperature

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
