one, Introduction

Soil detection sensor S-THEC-R-A-L2000, Using high-precision digital sensing chip combined with embedded processing and calculation, the temperature, moisture and conductivity of the soil are collected and measured ( EC）， It has the characteristics of high sensitivity, accurate measurement, stable performance, low power consumption, good weather resistance, and easy to use. It can be widely used in many industries such as agriculture, forestry and horticulture.

Before leaving the factory, the temperature coefficient calibration and soil moisture accuracy and conductivity accuracy calibration are carried out to ensure that customers can directly collect data when using it.This product is based on RS485 Standard communication of serial bus, strong anti-interference ability.
