Pedal Based Hand Washing Machine with Water Level Indicator
ABSTRACT:The rate of increase in the spread of communicable diseases in our society necessitated the need for an efficient mechanism to provide proper hygiene. Hand hygiene is the most effective means of preventing the spread of these diseases. Therefore, this study presents the development of a pedal based hand washing machine for the sole purpose of hand washing. The proposed system incorporates the standard mechanical hand washing machine with digital water level indicator. The mechanical part of the system employed the use of primer pumps attached to the foot pedals to dispense water and soap through different outlets. In addition, an Arduino based water level indicator which comprises of ultrasonic sensor and liquid-crystal display (LCD) is utilized to display the amount of water present in the reservoir. The developed system is easy to operate and can function under any weather condition.
