Abstract

The invention provides a water testing pen which interacts with a user terminal and comprises a TDS acquisition module, a control module and a short distance wireless communication module, wherein the TDS acquisition module is used for transmitting corresponding output frequency of a solution to be tested to the control module so as to enable the control module to process the output frequency; the control module is used for processing the output frequency so as to obtain a value of TDS, and used for transmitting the value of TDS to the short distance wireless communication module. The short distance wireless communication module is used for transmitting the value of the TDS to the user terminal so as to be checked by a user. Compared with a conventional water testing pen, the water testing pen provided by the embodiment of the invention is beneficial for the user to intuitively understand the quality of tested water.

Description

technical field [0001] The invention relates to the field of measurement, in particular to a water measuring pen. Background technique [0002] Water is the source of life, and human beings cannot do without water in production and life. In the Earth's hydrosphere, the available freshwater resources are only part of rivers, freshwater lakes and groundwater, less than 1% of the total. Nowadays, with the development of social economy, the progress of science and the improvement of people's living standards, environmental pollution is becoming more and more serious, among which, the pollution of water environment is the most serious. In today's increasingly scarce water resources, water quality issues have received more attention, so testing water quality can enable us to better protect water resources. [0003] However, the existing water measuring pens often need to manually check the readings displayed by the water measuring pens after the measurement is completed. Since t...
