Pulse Sensor Connection

Heart Pulse sensor is a heart-rate sensor for Arduino. We connect the sensor with Arduino and start to measure the number of beats per minute. When the heart beat status change from stable to critical, the Raspberry-pi sends a relevant message to the web services to deliver an Ambulance.
