Story

Our project uses the RFID unit to detect the user's pass to open the automated door, then the ENV II unit checks the user's bodyweight and temperature (built into the toilet seat). The user is then prompted with his/her weight and temperature, alerting them if they are overweight or having a fever. If the user's weight is over 90kg, the display will alert them that they are overweight. If the user's body temperature is above 37.5 degrees celsius, they are then prompted to see if they would like to schedule a doctor's appointment. The Light unit checks how hydrated the user is by detecting how much light passes through the user's urine, as the more concentrated the urine is, lesser light will pass through, so if less than 500 Lux is detected, the display will prompt the user to drink more water.
