Water Level Indicator and Temperature Controller
This study aimed to construct an auto filler tank that could be controlled by a stand-alone circuit that has a water-level indicator. The device would automatically fill the tank when the water level was at its minimum and would also automatically close the inlet when the water level was at its maximum. Also, the design had an automatic temperature controller that maintains the required temperature needed by the user. Experimental development and descriptive approaches   were the methods used. Two purposively chosen evaluators were requested to assess the functionality and practicality of the water level indicator and temperature controller. Findings showed that the device was helpful to the consumers because it was applicable for sterilization, heating and other applications involving water and temperature.
