Soil acidity and alkalinity monitoring method and device thereof

Abstract

The invention relates to a soil acidity and alkalinity monitoring method and a device thereof. The monitoring method mainly comprises the following steps: performing electrolysis treatment on a monitoring device, inserted into planted soil, and aqueous soil solution and producing hydrogen, combining hydrogen with a reaction layer of the monitoring device, thus obtaining the change of electrical conductivity of the reaction layer through the concentration change of hydrogen, and further obtaining the electrical conductivity value through electrodes on the monitoring device; comparing with the electrical conductivity data of soil suitable for planting in the cloud database through wireless transmission protocol and equipment, thus knowing whether the soil acidity and alkalinity is changed or not so as to ensure that the plant grows in the soil environment with predefined pH, and taking supplementation measures; the monitoring device comprises a monitoring body and a jacket containing the monitoring body, the monitoring body comprises a reaction layer combined with hydrogen, electrodes matched with the jacket for producing electrolysis reaction, and an electrical conductivity monitoring electrode, after hydrogen obtained by electrolyzing aqueous water solution is combined with the reaction layer of the monitoring body and as the electrical conductivity of the reaction layer is changed due to concentration change of hydrogen, the electrical conductivity value can be obtained by the monitoring electrode.

Description

technical field [0001] The present invention relates to a method and device for monitoring soil pH, especially refers to the change of electrical conductivity derived from the change of hydrogen concentration, through the wireless transmission protocol and equipment, and the electrical conductivity data suitable for planting soil in the matching cloud database In contrast, it is always guaranteed that the planted plants can grow in a soil environment with a predetermined pH, and supplementary measures can be taken immediately. Background technique [0002] Soil pH, commonly known as soil pH, the mathematical definition of pH is the concentration of hydrogen ions (Hydrogen Ion Concentration, H + ) negative logarithmic value, that is, the formula: pH=-log[H + ] as shown. Soil that is too acidic or too alkaline is an important reason that affects crop growth, causes plant element imbalance, and some diseases. However, the conditions required for soil pH are different among di...

Problems solved by technology

[0004] The above-mentioned conventional pH detectors relying on the electrochemical equilibrium reaction formula are sold on the market for about NT$2,000 or more. The coating film will be exhausted due to chemical reactions, and it cannot be inserted in the soil for a long time. After that, it needs to be soaked in the calibration solution every two weeks, and the instrument is re-calibrated. Even if it is not used continuously, the sensitivity of the measurement part in contact with the soil will no longer be trustworthy for about one year, and a new product needs to be purchased. , to measure the soil pH value; in view of the fact that many remote monitoring and control systems are used to assist green energy related industries, such as Taiwan’s previous case publication No. 201314636, No. 201424576, and No. 201513785 Prevalence; currently known various pH measurement / monitoring methods cannot be quickly and effectively applied to the current green energy related industries that are booming due to global warming
