In our daily small-scale planting of crops, we will not pay any attention to the effect of soil pH on crop growth. In our minds, there may not be the concept of soil pH, but through scientific experiments, soil pH has a huge impact on crop growth. For different crops, its roots adapt to the pH of the soil. Overacidity or overalkali will greatly reduce the effect of soil nutrients on crop growth.

The imbalance of acid and base will make the trace elements required by some plants cannot be effectively dissolved in the water and absorbed by the plant; the imbalance of acid and alkali will destroy the benign structure of the soil and cause the soil to lack some nutrients for plant growth; The activity of microorganisms that can convert organic matter in the soil is reduced, which will cause some substances in the soil to not be decomposed and cannot be absorbed by plants. In general, soil pH balance is a very important factor for crop growth.

Based on the soil pH test experiments at multiple bases, Xinxin Wulian has developed a new type of wireless soil pH sensor based on the actual pH range of the soil and research on the existing soil pH testers on the market. Our company's soil pH sensor (also known as soil conductivity sensor or soil pH tester) is a new generation of wireless sensors with world advanced level independently developed based on conductivity theory and using frequency domain measurement technology.

This soil pH sensor can accurately and quickly measure the conductivity characteristics of soil or other media, and then quickly convert this measured conductivity characteristic into a linearized standard voltage signal output, and display the current on the LED display in real time Measured data.

Our company's soil pH sensor can be used for real-time monitoring of soil / medium conductivity. At present this product has been widely used in agricultural irrigation, agricultural soil pH research, sand soil planting, soil pH measurement of concrete mixing.
