IoT-based Temperature Monitoring System For Affordable Healthcare Solutions

Real-time health monitoring is not possible in rural areas because healthcare facilities are usually limited in their availability. This paper proposes an Internet of Things (IoT)-based temperature measurement system aiming to offer a cost-effective and viable method of real-time body temperature measurement. The Arduino Uno processes the data, displays the current temperature on an I2C LCD display, and monitors temperature change with an NTC thermistor sensor. Through the use of a 10kΩ resistor and voltage divider circuit, the thermistor gives analog temperature information to the Arduino, which it uses the Steinhart-Hart equation to process It is simple to monitor as processing temperature indication is shown on the LCD panel The system is appropriately suited for potential use in remote healthcare due to its portability, cost-effectiveness, and simplicity to install. Moreover, its accuracy to ±0.5°C was contrasted with that of the commercial digital thermometers, thus proving its reliability. Even though the Lambert system is currently a standalone device, transmission of data for remote monitoring could be enhanced in the future, through Bluetooth or Wi-Fi. Overall, this Internet of Things temperature measurement system is a cost-effective, affordable, and effective healthcare system, especially for the poor and rural areas, which helps to acquire better patient treatment and early diagnosis.
