碩士 === 輔仁大學 === 電機工程學系碩士班 === 107 === When an user props up the tray while walking the tray often vibrates and liquids may splash out. This proposal is an improved design of an automatic detection of warning balance tray (ADWBT) by using a triaxial accelerometer module, force-sensitive resistors (FSR), four servo motors, LCD display, LEDs, and an MCU expansion board. The triaxial accelerometer module detects the tilt angle of the tray. The MCU expansion board controls the servo motors which are utilized to balance the tray. The FSRs in the tray will sense the carried item positions. The LEDs on the tray display the weight distribution and the location of the items carried to alert the user to prevent items on the tray from falling.
