A Portable Self-Monitoring Fitness System

The aim of the project is to make a real time wearable calorie monitoring system. The devices used in this project are 28 pin Microchip 8 bit microcontroller PIC16F1783, an alphanumeric LCD, keypad with four keys, an accelerometer, a buzzer, a RTC and a heart rate sensor. The system is battery operated. The battery can be charged using a 12Vdc adapter. The inputs to the controller are keys, accelerometer, heart rate sensor, RTC and the outputs to the system are LCD display and a buzzer. The user has to enter his/her current weight  using the keys on the keypad. The parameters will be saved in the RAM of the microcontroller. Then the system will list out the exercises. The user can select the exercise which will be displayed on LCD by using the keys. The heart beat rate sensor will continuously monitor the user’s heart beat and will warn by the glow of green LED if the heart rate is above the normal threshold. If the person's heart rate is in normal range and if he/she is performing the exercise then the red LED flashes.  The accelerometer will sense the amount of movement done by the user. After completing the exercise the system will be displaying the amount of calories burned by the user for the current day and a 'Congratulations' message will be displayed on the LCD. The RTC will give the time and date once it is configured. The RTC configuration should  be done at the initial startup of the system.
