This heart beat sensor is designed to give digital output of heart beat when a finger is placed on it. When the heartbeat detector is working, the top-most LED flashes with each heart beat. This digital output can be connected to microcontroller directly to measure the Beats Per Minute (BPM) rate. It works on the principle of light modulation by blood flow through finger at each pulse. Module dual output mode, digital output is simple, serial output with exact readings.
This Paper analyses about different stabilizing topology and different design which is based upon tapping the relay for different supply voltages to get nearly 220V value for each variation of supply to drive the load risk freely, thus stabilizing the output voltage.
