ES107-Soil-RS485 | ES107-Soil-USB
  1.  Soil Doctor- Smart Agriculture Monitoring for Soil 7 Elements, RS485 or USB for Android Mobile phone

Achieving optimal soil conditions is essential for maximizing crop yields and ensuring sustainable farming. WoMaster introduces the ES107-Soil Series, an advanced soil sensor designed to provide real-time monitoring of Electrical Conductivity (EC), pH, Nutrient Levels (N-P-K), Temperature, and Moisture. By delivering precise data on these critical factors, the ES107-Soil sensor empowers farmers to optimize fertilization, improve water management, and enhance overall soil health for more efficient and productive agriculture.
