Is it possible to monitor any person’s activity without using any wearable and breaking their privacy?
If you are a doctor or spy and asked to monitor the person’s health movements but you can’t use the camera in the washroom and wearable sensors on the body while bathing or showering.
So to solve this limitation, we designed a device that uses the radar sensor and the waves that detect human motion activity and vitals like respiration rate, heartbeat, pulse, etc.
Now you can monitor the person’s activity even when they shower.
Here we are using a 24HZ mm-wave sensor that detects actions and also tells the pulse and breathing rate. If you are trying to get the vitals like a heartbeat, pulse rate, and other vitals, then you can use the 6HZ sensor.
So here is the list of all the components that you need to make this project.
Bill of Material
After this, we can create the code to detect the actions.
Initially, we initiate the software serial for interfacing with the radar. Then, we create a loop function that reads the data received from the radar sensor and analyzes it by implementing an algorithm to detect human activities and states. The system provides output through the serial port, indicating whether the person is sleeping, running, moving, sitting, reading, or walking, and also reports their breathing rate.
Testing and Working
After uploading the code open the serial monitor and check the reading open the serial port and then you can see the readings.
