Novel design for conserving water: integrated efficient ablution and hygienic hand wash system

Abstract

The project is a conceptual integrated design of an efficient and health-effective product for daily use, especially in health sector. This project aims to design a water-sustaining via infectious diseases-protect product. The product is an integrated system with hand-wash, normal tab and ablution systems. This invention differs from existing technologies because the product does not use any hand contact when using soap to hand wash, water to rinse the hand and also when performing Ablution. Infrared sensors are used to change the mode state whether user want to use normal mode, Ablution mode or hand washing mode. Research on detection sensitivity detected by infrared sensors to any objects in front of the sensor have been done and PIC 18F4580 microcontroller is used to control the output of the infrared sensor to activate valves and pumps to drain out the soap and water. With this product, users can reduce up to 70% of water consumption. Methodology and results are explained in the paper.
