We created a biological parameter monitoring system using the Node MCU to track body temperature, heart rate, and oxygen saturation level (SpO2) data in this paper. The sensors that detect these signals are called sensors. We created the requisite signal conditioning circuits in our lab using off-the-shelf electronic components. The ESP 32 Node MCU-based data collecting system was created to collect relevant biological parameters. The prototype produced is a low-cost alternative to commercially available biological parameter monitoring devices. The necessary processing code is written in C and uploaded to the Node MCU using the Arduino IDE. On the OLED display module, all of the gathered parameters were presented. The devised technology was put to the test on 50 people of various ages and genders. The collected results were subjected to an error analysis. The prototype reveals that the system's accuracy for measured parameters is 98 percent. The system is designed for portability, high functionality, and low cost, making it an easily accessible tool for the general public, clinical environments, and other medical applications.
