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.

Electrode Maintenance:
PH electrode is not used at ordinary times and can be soaked in 3mol/l KCL solution or saturated KCL solution. It is strictly prohibited to immerse the electrode in distilled water and deionize the water or tap water with minimal plasma content.If the PH electrode is contaminated with inorganic substances, it can be cleaned with 0.1mol/l Hcl or NaOH solution for a few minutes and then washed with distilled water. If the PH electrode is contaminated with organic substances, it can be cleaned with alcohol or acetone and then cleaned with distilled water.(note: the protective cap before the electrode should be removed when using);
Clean the electrode with tap water every 3 months or 6 months according to the working environment.
