Soil Sensor
Traditionally, soil properties can be divided into physical properties, chemical properties and biological properties. Correspondingly, soil sensors can also be roughly divided into physical, chemical, biological, three categories.

Physical sensors can sense the changes of physical parameters of the object under test, such as temperature sensors, soil moisture sensors, pressure sensors, etc.

Chemical sensors can sense the changes of elements ions, such as pH electrodes.

Biosensors are mainly based on bioelectrochemical theory and can sense changes in biological information, such as enzyme sensors.

Because soil physical properties are more suitable for physical methods, the detection of physical properties has always been the focus of soil sensor research. Among them, the monitoring of soil moisture and temperature is the most important, and the corresponding technology is more mature. Some progress has also been made in the research of chemical properties sensors.

More attention has been paid to soil acidity and alkalinity, redox potential and salinity, and the research of soil nutrients and organic matter sensor technology is relatively weak. However, the research on the application of biological sensors in soil detection is still very deficient.
