| Summary: | In today’s world, HVAC system are widely used and the performance of the
temperature sensor such as thermistors are very important since the poor accuracy in
measurement can yield to unreliable performance of the system. Therefore it is
necessary to calibrate the thermistors accordingly. There are various ways to perform
the calibration and each has different kinds of limitation. One outstanding approach
is to design a portable calibrator with water bath with two chambers which can result
in high accuracy and rapid calibration. The disadvantage of the current model is
adding the liquid in the tank manually. This report is about designing an intelligent
water level controller. A simulation of microcontroller based water level controller
and a prototype will be discussed. In order to get a reliable performance, the
accuracy of measuring the water level is of vital importance. |
