Abstract: This paper propose a swimming safety tracker system is designed using Internet of Things (IoT). The proposed system is really helpful for preventing accidents when swimming to save lives. The Dip sensor is used to determine whether a person is above or below the water by sending signals to the detector circuit via a sensor. An amplifier receives the output signal for additional amplification. A/D converter is given the signal that has been enhanced. When the sensor is in a dip situation, the microcontroller begin the internal timer. RF transmitter receives the signal that has been amplified. The sensor provides the transmitter with the corresponding voltage signal as soon as the RF receiver picks up the signal that sends data to the Node MCU. The received signal calculate by microcontroller. Here the microcontroller is the flash type reprogrammable microcontroller in which we have already programmed with IOT cloud server link. Then the microcontroller received the monitored parameter from the RF receiver. These data send to cloud database for retrieve in any were by IOT and identify the DIP person for make alert sound. The proposed system gives optimal results when compared to other traditional approaches.
