Sugar - Altitude Pressure Module

Signal：Timing signal - I2C protocol

Module principle

The Earth has gravity, and the closer an object is to the center of the earth, the stronger the gravitational force it receives. Therefore, there is a certain linear relationship between the gravitational force an object receives and its height relative to the earth. The barometric altimeter makes use of this principle by measuring atmospheric pressure with a pressure sensor and indirectly calculating the altitude based on the relationship between pressure and altitude.

Program-Function Description

1、Set the color screen to full-color pixel mode and turn off the automatic refresh mode

2、Read the temperature value for judgment, and set this threshold according to actual needsHere, 28 is used as an example for judgment

3、Display the various data of the module on the color screen. Since the data read is decimal, it needs to be converted to a string before it can be displayed on the screen
