Soil pH Sensors

Every plant has an ideal soil pH range for optimal growth, and most plants face challenges if the pH is too high or too low. Using a soil pH sensor to measure acidity or alkalinity promotes healthy crop development and helps reduce pest and disease problems. As a result, soil pH testing is vital for effective agriculture.

Soil pH sensors assess the acidity or alkalinity of soil by measuring the concentration of hydrogen ions (pH) and converting this information into a usable output signal. These sensors consist of two or more electrodes inserted vertically into the soil, where they create an electrochemical reaction. This reaction is then converted into an electrical signal that can be transmitted to the user or an agricultural management system for analysis.

Soil pH sensors are utilized in agriculture to assist farmers in making informed planting decisions, applying fertilizers more effectively, enhancing fertilizer efficiency, and protecting the environment.
