Wireless Health and Security Monitor That Does Not Breach Privacy

Some patients and senior citizens require continuous monitoring, but it cannot be done through CCTV cameras in their bathrooms or even bedrooms as it affects their privacy. The same applies to prisoners and some other cases. This project would help you design a device that lets you monitor the person’s health data like respiration and the activity being done, such as sleeping, walking, reading, and moving, without the use of a camera.

Fig. 1 shows the author’s prototype with the screen showing the activity being done. The components required to build this device are listed under the Bill of Material table.

Software

First, you need to add the ESP board to Arduino IDE. To install the Arduino IDE, you can follow the instructions on the ESP website. You need to install and add the library for radar interfacing, so download and add the library with this link.

Then install the ESP Dash library to the host page having a dashboard to show real-time data of the person’s activity and vitals through Wi-Fi. You need to modify the library and do some settings to access the RX2 and TX2 pins of the ESP board so that you would be able to get the radar readings through the serial port (see Fig. 2).

So, first, open the library folder and then open the library main ccp file, and under that do the setting and add the code shown in Fig. 3. After modifying the library code, save it.
