    Design and development of automatic water boiler system model with programmable intelligent computer (PIC)
    (Terengganu: Universiti Malaysia Terengganu, 2009) Khaw Wei Kiat
    Nowadays, the water boiler is a popular product. There are many types of water boilers in the market. However for most of the products, water has to be refilled into water boiler manually before using it. This project is done to fabricate an automatic water boiler system model to improve the current water boiler. The water boiler can refill and boil the water automatically. PIC 16F877 A has been selected to be used in this project as to control the system flows. The temperature sensor (LM35) is used to sense the water temperature and the water level sensors are used to sense the water level in the water boiler and control the water refilling process. In order to fabricate out the product, both the software model and hardware model are completed. The software model is done by writing a source code for the system. The software model is evaluated by using the MIN140 PIC Training Kit, BZ022. For the hardware model, the circuits of the product are designed and fabricated out by soldering all the components on the strip board. The circuits are then assembled into a complete model. The model is packaged in a cabinet with vessel.
