STRUCTURE OF WATER LEVEL SENSOR |
摘要 |
PURPOSE: A structure of a water level sensor is provided to measure level of various kinds of solution having different permittivity. CONSTITUTION: A structure of a water level sensor comprises a capacitance sensor and a signal processing unit. The capacitance sensor comprises a first electrode and a second electrode. The first electrode and second electrode are formed on multiple sections to be separated as a fixed distance. The signal processing unit is electrically connected to the first electrode and the second electrode. The signal processing unit detects the water level according to a sensing signal which is generated base on the change of electrostatic capacity at the capacitance sensor. The signal processing unit outputs a detection signal.
