Temperature sensor
Getting the temperature of the environment.
Ex17_01 Tracking temperature changing
Use "serial write line" code block to display temperature value.
1
In the "show data" interface, download the logging of temperature data.
2
Submit the downloaded ".txt" file, name it as "99_name_f3X_ex17_01.txt"

Ex17_02 Temperature Min & Max Values
Use "serial write line" code block to track temperature values.
1
Declared min & max variables to store the temperature data.
2
Checking the current temperature with two if conditions, they are higher than the storing max variable value and lower than the min variable value.
3
Press the A button to display the highest temperature the sensor detected.
4
Press the B button to show the lowest temperature the sensor detected.
