Body Temperature Distribution Monitor Interfaced with Wi-Fi for Wireless Transmission of Data: Design and Comparative Study

With advancements in technology and people being more conscious about their health than ever, technical improvements in the field of medicine and biotechnology are inevitable. People are switching towards wearable devices to keep track of their health and fitness related data. This project investigates the development of a monitor to keep track of the distribution of body temperature. The report presents the development of a temperature monitor interfaced with a Wi-Fi module to wirelessly view related data on a smartphone; any other Wi-Fi compatible device or any device with Internet connectivity. The temperature monitor developed uses the LM35 temperature sensor to calculate the temperature every second. The sensor module developed is then interfaced with an Atmega 328 microcontroller responsible for calculating the temperature. It then transfers the serial data to ESP8266 Wi-Fi module, which transmits the data to Blynk Internet server. The results also show that the temperature is successfully transferred over Wi-Fi and could be helpful in emergency or monitoring situations
