Overview
We were tasked to make use of the embedded sensors found on the SensorTag CC2650 to detect ambient light changes and movement.
The CC2650 SensorTag board has a Motion Senor MPU9250 and a light sensor OPT 3001. Your task is to read the light and MPU sensors (accelerometer only) at different rates based on the environment, and change the LED brightness according to the light sensor and the accelerometer values. In particular, you should adjust the brightness of the LED depending on how fast the sensor node is moving and/or the strength of the light shining on the sensor node. As increasing the brightness of the LED contributes towards the light shining on the light sensor, you need to adjust the thresholds of the light sensor values appropriately.
In our proposed solution, we are using the sensors mentioned above for this project.
