INTRODUCTION
Heartbeat sensor. It is a noninvasive type biomedical sensor which works on Principle of Infrared light propagation through Human Blood. It gives a digital Pulse output (+5V) every time a Heart Beats. It works on +5 volt DC supply. Heart beat sensor gives digital Pulse outputs of heat beat when a finger is placed on it. When the heart beat is detected, the output beat LED flashes in union with each heartbeat. This digital output can be connected to microcontroller directly to measure the Beats per Minute (BPM) rate. Analog output can be used to show waveform of heart beats. It works on the principle of Light modulation by blood flow due to heart beat through finger at each pulse.
FEATURES
• Operating voltage: 5V DC • Output pattern: Pulsating DC Works on IR sensor principle • Suitable for measuring the pulse rate easily • Easy to operate.
ADVANTAGES
• Digital pattern output will help in easy understanding to the user. • Patient can analyse his/her pulse rate very easily as it is a digital sensor
APPLICATION
• Patient monitoring system • Digital heart beat monitoring • Useful in domestic as it can be monitored easily. • Bio-logical feedback for Robotics and controls
