In this paper we describe the design process of a low cost and portable microcontroller based heart-rate counting and temperature measurement system for monitoring health condition. The raw heart-rate signals were collected from finger using IR TX-RX (Infrared Transmitter and Receiver pair) module which was amplified in order to convert them to an observable scale. The inherent noise signal was then eliminated using a low pass filter. These signals were counted by a microcontroller and displayed on the LCD panel. As well as the LM35 measure the temperature in the form of voltage and it convert into digital form using ADC 0804 and display on LCD. The project is applicable for family, hospital, clinic, community medical treatment, sports healthcare and other medical purposes. Also, fit for the adults and the pediatrics. However, presented method in the developed system needs further investigation and need more functionality, which may be useful to consider advance in future research.
