Abstract

The invention discloses a solution color sensor. The sensor comprises a cassette, an observation vessel and a photoelectric transducer. The cassette is provided with a through hole. The observation vessel and the photoelectric transducer, which directly face to each other, are arranged in the cassette. The observation vessel adopts a transparent sealing plate and a vessel wall is provided with anopening used for connecting a water inlet pipe and a water outlet pipe. The water inlet pipe and the water outlet pipe pass through a through hole and then are extended to the external portion of thecassette. The photoelectric transducer is formed by a cold light source and a measurement electrode with a current frequency converter. Under a cold light source effect, the measurement electrode carries out color detection on a solution to be measured which is introduced by the water inlet pipe in the observation vessel, acquires a detection signal and converts into an electric signal formed by values on R, G and B channels, and then outputs. In the invention, solution color dynamic measurement can be completed, the maintenance cost of the sensor is reduced, the sensor is not interfered by ambient light, detection precision is high, cost is low and the structure is reliable.

Description

technical field [0001] The invention relates to a solution color sensor and belongs to the technical field of sensors. Background technique [0002] With the development of the Internet of Things technology, various types of sensors have replaced a large amount of measurement work that had to be done manually in the past, improving production efficiency and reducing the risk of errors that may be caused by human factors. However, the existing color sensors on the market are mostly used in logistics sorting, publishing and printing industries, and there is no corresponding technical solution for the quantitative detection of solution color. [0003] In scenarios such as pond industrial farming and field environmental index monitoring, it is often necessary to use various color reaction reagents and test papers for qualitative or quantitative detection of solution samples. The operation procedure of this kind of reaction is simple, no professional training is required, and th...
