The project involves designing and developing a wearable device that tracks heartbeats and transmits the data to an online database for monitoring. The device uses op-amps to create a low-pass filter, which picks up and removes unwanted signals, and a comparator sets the reference voltage at 0.3V. The heartbeat signal is then transmitted to a microcontroller for analysis. The project was completed in a year, and the device can be used to track health remotely, monitor patient vital signs, or even screen seniors' health from home.
