In this study, portable and low cost heart beat rate measurement device has been designed with using PIC 16F877. It measures heart beat rates from finger using optical sensors and the rate is then averaged and displayed on a text based LCD. The finger tip probe has been selected from commercial products. The device works with 1 x 9V battery. Also it measures ambient temperature and humidity in addition to heart beat. The measurement accuracy is acceptable. The hardware that has been designed in this study is available for checking the pulse with education purpose. The hardware can be improved adding wireless data transfer devices in telemedicine applications. The device has the advantage that it can be used by nonprofessional people at home to measure the heart rate easily and safely. This paper report describes how to build a digital heart-rate monitor using a PIC 16F877 microcontroller (MCU). The heart beat rate per minute is displayed on an LCD. Keywords: biomedical instrumentation, heart rate measurement, bio electronic, PIC 16F877
