Soil Sensors – Rika

Soil Sensor

Sensors that detect soil conditions have become an important tool for modern farmers in crop production. The benefits of soil sensor are obvious. Due to differences in electrical resistance or electrical conductivity, information on soil moisture and soil particle composition can be clearly reflected, as well as intuitive conclusions on density, pH, salinity/conductivity and temperature. Through the network construction on the farm, the real-time parameters collected by the soil sensor are transmitted to the computer mainframe and connected with the system installed on the machine to realize automatic control spraying of fertilizer and pesticide. Welcome to contact for further information on soil temperature moisture sensor.
