Abstract

• The main purpose of this research work is intended to measure the blood pressure and body temperature of human body. The Arduino microcontroller Uno board, heart beat sensor, Temperature sensor (LM-35) and 20x4 Liquid Crystal Display are responsible for reliable operation. Heart beat sensor senses the blood pressure and temperature sensor senses the temperature of the body for human. The obtainable data from the sensors are sent to the Arduino microcontroller. Arduino microcontroller Uno board is used as main control circuit of this system. The software code for the proposed system is written by using C programming Language. The output is on the Liquid Crystal Display and serial plotter. Blood pressure and body temperature are very important for human body. The developed device is shown acceptable outcomes when compared with other measuring devices.
