  1. 1. MICROCONTROLLER BASED HEART RATE METER CHETANA NAIR PALLAVI SURYAVANSHI RUCHI SOAM SANGEETA CHALWADI
  2. 2. CONTENT • INTRODUCTION • BLOCK DIAGRAM • DESCRIPTION • CIRCUIT DIAGRAM • ADVANTAGES & DISADVANTAGES • APPLICATIONS • FUTURE SCOPE
  3. 3. INTRODUCTION This project explains how a single chip microcontroller can be used to analyze heart beat rate signals in real time. Here heart rate is measured by employing the pulse method i.e blood flow into the finger.
  4. 4. BLOCK DIAGRAM AMPLIFIER & FILTER MICROCONT ROLLER BUFFER DISPLAY CLOCK POWER SUPPLY
  5. 5. DESCRIPTION • When blood flows during the systolic stroke of the heart, the finger gets its blood via radial artery of the arm. • The blood flow into the finger can be sensed photo electrically using LDR. • The photocurrent is converted into voltage and amplified by an operational amplifier. • The microcontroller processes the signal and the heart rate is displayed using 7-segment display.
  6. 6. PROCESS
  7. 7. HARDWARE DESCRIPTION
  8. 8. ADVANTAGES & DISADVANTAGES • PORTABLE • LOW POWER CONSUMPTION • EASY TO USE • NOT PRECISE • REQUIRES A LIGHT SOURCE
  9. 9. APPLICATIONS • HEART RATE MONITORING IN FITNESS CENTER. • FOR ATHELETES • IN RURAL AREAS WHERE MEDICAL FACILITIES ARE LIMITED.
  10. 10. FUTURE SCOPE • STORING THE HEART RATE IN A MEMORY. • CONNECTING WITH E-MAIL TO SEND ALERT MESSAGES. • INCLUDING OTHER BIO- MEDICAL SIGNALS LIKE BREATHING RATE ALONG WITH HEART RATE.
