Abstract: “Silla de-ruedas” This project describes the design of a simple, wheel chair using head movement system. Heart rate of the subject is measured from the thumb finger using IRD (Infra-Red Device sensors). This instrument employs a simple Opto electronic sensor, conveniently strapped on the finger, to give continuous indication of the pulse digits. The Pulse monitor works both on battery or mains supply. It is ideal for continuous monitoring in operation theatres, I.C. units, biomedical/human engineering studies and sports medicine.This project uses AT89S52 MCU as its controller. By reading all the values of temperature and heart rate will be displayed on LCD. Temperature and heart beat values will be taken and updated in the web server using IoT module interfaced to the controller. This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step down transformer
