This device helps to detect the symptoms of COVID-19, so as to help individuals quarantine themselves and practice social distancing. The DIY works by detecting the basic symptoms of the virus, which are: increased body temperature and shortness of breath. Although it is not necessary that shortness of breath will cause low levels of oxygen in your blood in general cases, coronavirus causes infection in your lungs which leads to low oxygen level or hypoxia.
So, today in our device we will try to look for these symptoms of the virus to detect potential suspects, so that they can get a further check-up for confirmation.
we will be checking for two symptoms: raised body temperature, and blood oxygen percentage.How does Our COVID-19 Suspect Detection Device work?
- First, it checks the temperature of the body using a sensor.
- Next, if it detects that temperature is higher than usual then it passes the first symptom to positive, indicating the symptom on OLED display as s1 +
- Then, using the Max30100 sensor it monitors the heartbeat and oxygen percentage
- If the device calculates that the oxygen percentage in the blood is below the normal oxygen level then the device passes the second symptom as well, indicating the symptom on OLED display as s2 +
If both the symptoms are positive, the person might have contracted the virus and can be taken to a hospital for confirmation and treatment.
For this, we need two types of sensors. The first one is for temperature measurement. Here I am using a Mpu6050 sensor. You might laugh at me or call me crazy because it’s a sensor for acceleration measurement not fit for temperature measurement but through personal testing, I’ve found that it gives a roughly accurate result, although I do recommend you use any good dedicated temperature sensor, such as Lm 35.
For blood oxygen percentage calculation I am using the Max30100 sensor.
So we start our project by collecting the following components.Software
First, we have to used the Arduino IDE and its library (MPU6050, u8g2, Max30100) in code
