Good day to you.

I am working on a project to detect sleeping disorder mainly focusing on “sleep apnea”.Sleep apnoea syndrome (SAS) is a disease consisting in the nocturnal cessation of oronasal airflow at least 10 seconds in duration. My goal is to detect this syndrome and visualize on a mobile application for the patient. Projects done in the past detect snoring to check whether the patient has SAS or not.

In my scenario, i would like to detect the snoring sound and rectify it by sending a buzzer sound to distract the patient during sleep. The issue that i am facing is choosing the right sensors before making any purchase and that’s where i am looking for some guidance.

  • Hi, thank you for your prompt reply. My idea is that when patient starts snoring a buzzer goes off to distract them. The snoring will be calculated in decibels and given range. So which sensors will go with RaspberryPi to detect snoring sound and buzzer and later how can i visualize them on mobile app. I will appreciate your guidance. 🙂 – Abdullah Khalid Mahmood 1 hour ago
  • Ah, you started a board question, narrowing down to very specifics. Your broad question falls in area of Enggr Systems Analysis and Design (see Refs 6 ~10) of my answer. The old Water Fall methodology usually starts with (1) User Requirements, (2) Functional Specifications. The new methodology usually goes Agile, or meddling through. Now you have briefly described your user requirement and functional spec. But they are too brief. Usually you need to write up a project proposal, or set up a GitHub. You might like to visit Cornell U, to see how enggr students do Rpi group projects. – tlfong01 28 mins ago    
  • This RpiSO is a short Q&A thing, not a forum for discussions. For long discussions and project type forums you can visit rpi.org.forum where there are forums for newbies and Sensor & Automation etc. You can my old answers about home automation there. You can search “hx711”, “weight sensor”, “tlfong01” for my scattered answers. – tlfong01 21 mins ago   
  • For example, if you search “buzzer” “sound”, “tlfong01”, you can find the following posts to START your research. You may also like to visit “electronics tutorials” to update your electronics knowledge.

  • But of course you can ask short Q&A of Rpi related questions, such as “How can Rpi python with ADC detect and record snoring sound?” Then I can give you answer such as: I would suggest to use the following:(1) DS3231 Real Time Clock, (2) HX711 ADC, (3) xyz weight sensor etc etc,… – tlfong01 27 secs ago   Edit
