DIGITAL ANGLE MEASURING SENSOR AND A DEVICE THEREOF USING A SENSING PAD IN WHICH CURRENT FLOWS THROUGH LIQUID CAPABLE OF EMBODYING A STABLE AND SIMPLE CIRCUIT THROUGH A DIGITAL METHOD

摘要

PURPOSE: A digital angle measuring sensor and a device thereof using a sensing pad in which current flows through liquid are provided to improve the accuracy, digital and slope compensation comparing with an existing sensing mode by measuring the exact amount of the liquid through a digital mode.;CONSTITUTION: A digital angle measuring sensor using a sensing pad in which current flows through liquid comprises a pad detecting unit and a height measuring unit and a quantity calculation unit. When the pad detection unit measures the height, an electric signal is added to a specific pad and the electricity is flowed between pads through the liquid. The electrically connected pads are detected. The height measuring unit detects the touching or non-touching pad with the liquid, the height of the liquid is measured. The quantity calculation unit calculates the quantity according to the height in consideration of the shape of the container.;COPYRIGHT KIPO 2012
