In this section, you will program Amazon FreeRTOS to use the sensors on the CC3220SF-LAUNCHXL board. First, you will be able to get the temperature sensor readings from the board and send to AWS IoT Core. Next, you will get the accelerometer sensor readings and send to AWS IoT Core. You will then learn how to use Rules Engine to send an alert to your mobile phone when the board tilts beyond a 45-degree angle.
