Through last week’s brainstorming in class, I decided to switch to VL53L0X which detects the longer distance of up to 2 meters. I decide to use it to monitor the distance between the user’s head to the monitor. I think it could be a helpful device for me since I have had serious cervical spondylosis for a long time. 

I set the threshold value of 40 cm, and if my head is close to the laptop’s screen within 40cm the white led will light on to give the warning. And I modified my dashboard consistent with my monitoring scenario. And added a blue led for the status of the wifi connection, and a button and yellow led for the broker’s connection.

I made an enclosure for it as my assignment for fabrication class, it’s not the ideal piece. I supposed it should be at the same height as my head and be put after the laptop.

Questions:

The device has to monitor data during spring break, where and how to store the data? Each time I re-plug the device, the data will be renewed and history data not shown anymore.
