Help to chose components

I hope this message finds you well. I am reaching out to seek some guidance with my first Arduino project.

To give you some context, I am new to Arduino and I am looking to create a night respiratory device monitoring system. I believe the best way to determine if the device is in use is to measure its electrical consumption. The device is connected to the network through an AC/DC converter, so I am considering using a current sensor before the AC/DC converter. Alternatively, I could use a combination of a current sensor and a noise sensor on the device itself to detect the sound of airflow. Additionally, a light sensor could also be used to detect whether the lights are on or off in the room.

Furthermore, I understand that the device will consume different levels of power depending on its operation ('idle' consumption +/- warmer/humidifier +/- flow generator). Therefore, I plan to measure these different consumption levels and integrate them into the code.

My main objective is to issue an alert when the device is not used during the night. My approach is to calculate the time since the device was started, and if the device is still in idle mode (+/- warmer/humidifier) after, say, one hour, an alert should be issued. The alert will be in the form of a vibrating device, similar to a smartphone, to avoid disturbing others in the household.

I am confident in my ability to write the code, but I require assistance in choosing the right components to use. Specifically, I would appreciate your guidance in selecting the following components:

  • Current measurement sensor
  • Noise sensor
  • Light sensor
  • Display to show the actual current consumption or chosen delay before vibration alert
  • Vibrating device
  • Button to switch between possible delays

Thank you for your time and assistance.

Best regards,

A proper selection of these sensors can be done from your side only.

You know all given system requirements.

Make sure you master making non-blocking delays and State Machines before you start writing your code.

One thing if this is life critical then you should not be doing it !

Good advice. Thank you.
