Cardiac monitoring devices can assist doctors and patients in tracking a patient's cardiac health over time. They can also detect irregularities in heart rhythms that may indicate a heart condition such as Atrial Fibrillation (AF). The cardiac monitor's hardware is straightforward and simple. The device's main controller, along with the max 30102 pulse oximeter, is the ESP8266 microcontroller. The Arduino IDE is used to programme it. The Wi-Fi module transmits data wirelessly from the phone to the microcontroller and vice versa. After installing the android mobile phone app, the device can wirelessly connect to the mobile phone's Wi-Fi, and the user can see his heartbeat, body temperature, and blood oxygen levels on the device's OLED screen. Additionally, vitals data can be saved in the user's cell phone for later analysis or sent to the cloud for further analysis by the doctor. The Esp8266 microcontroller controls the phone's functions and displays the device's vitals data on the phone's screen. Following the transmission of cardiac device data to the phone, the app calculates the heart beat time and sends the result to the phone screen, which is displayed on the devices OLED
