Problems solved by technology

In the existing technology, most of the floating ball level sensors are used, but the floating ball type is realized by mechanical power, and the floating ball itself has a certain gravity. The floating ball is located under the water surface, and the measurement is not accurate. Therefore, there is room for improvement.

Abstract

The invention discloses an electronic liquid level sensor. The electronic liquid level sensor comprises a battery, a switch, a first resistor to a ninth resistor, a first capacitor to a fifth capacitor, a first light emitting diode to a fourth light emitting diode, a first detection chip, a second detection chip, a probe and a loudspeaker. Compared with the prior art, contact type detection is adopted, the probe is directly located in liquid for detection, a plurality of detection points can be arranged according to needs, and therefore detection requirements of different depths are met, detection precision is improved through direct contact with the liquid, the water level height is electronically displayed, use is convenient, and application and popularization value is achieved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an electronic liquid level sensor. Background technique [0002] A liquid level sensor is a pressure sensor that measures liquid level. In the existing technology, most of the floating ball level sensors are used, but the floating ball type is realized by mechanical power, and the floating ball itself has a certain gravity. The floating ball is located under the water surface, and the measurement is not accurate. Therefore, there is room for improvement. Contents of the invention [0003] The object of the present invention is to provide an electronic liquid level sensor in order to solve the above problems. [0004] The present invention achieves the above object through the following technical solutions: [0005] The invention includes a battery, a switch, a first resistor to a ninth resistor, a first capacitor to a fifth capacitor, a first light emitting diode to a fou...
