The main idea of the paper is to get individuals to monitor their body mass index (BMI) and temperature. The BMI is a technique used to test people for potential weight issues and to track the weight status of people. Body mass index is calculated by using two main parameters they are height and weight of the person. We develop a commercial device, which calculates the BMI of the user with their respective height and weight. When the user stands in front of the device, The device scans the user’s face and classifies the user’s gender as correct BMI of user is dependent on gender, Later the height is calculated using ultrasonic sensor and weight is also measured. The device also shows the temperature and this temperature is measured by MLX 90614 sensor Now the device calculates the BMI and displays the user’s BMI to the user. The device also displays some message to the user according to their BMI, such as whether the person is over weighted or low weighted.
