Heart rate monitor - latha s - 10-04-2017 Heart Rate Monitor Abstract The aim of this project is to implement an ECG and Digital Heart Rate counter. amplifying the desired weak signal from the heart and isolating this from the noise signal from the muscles were the main challenges. A display of the heart rate will also be implemented.The time between signal peaks will be calculated and then the frequency of the peaks will be obtained. Attempt is made to make the device portable. low cost amplifier and filter components were used and it also includes the microcontroller and LCD screen. Design The main challenge is to amplify the desired weak signal in the presence of noise from other muscles and electrical sources. Desired signal the range of about 2mV is the voltage range picked up by the electrodes at the skin surface. Noise External interferences like 50Hz from power lines and emf s from fluorescent lights will affect the picked up signal. Muscles other than the heart also produce voltage potentials. Block diagram The major blocks in this project are 1)amplifier and filter 2)ADC 3)Microcontroller 4)Display 5)Clock 6)Voltage regulator 7)Battery Amplification Stage An instrumentation amp of high gain and high Common Rejection Ratio (CMRR) is used to amplify the weak signals. Processing & Display the output signal produced by the amplification stage is processed by an 8 bit microcontroller. Microchip PIC16F877A microcontroller is used. An liquid crystal display (LCD) module is used to display the beats. Power 9V battery is used to power the circuit. The required 5V is obtained via a LM7805 5V voltage regulator.

The report is available at: http://seminarsprojects.net/Thread-heart-rate-monitor--15143 Heart rate monitor - abhimanyu_thakur18 - 10-04-2017 May i know what type of amplifier u using for this circuit? How many times of gain u amplfy? Thanks.. |
