Features： 1、The protection grade is IP68, which can be buried in the soil for a long time, resistant to long?term electrolysis, corrosion, vacuum filling and sealing, completely waterproof. 2、The soil moisture temperature humidity sensor is suitable for the measurement of soil temperature and moisture, with high precision, quick response and stable output. 3、This soil moisture sensor is less affected by soil salt content, and is suitable for all kinds of soil. 4、Analog output is adopted, which is flexible and can output current type or voltage type. Three wire system can be used for wiring. 5、It is widely used in scientific experiments, water?saving irrigation, greenhouse, flowers and vegetables, grassland and pasture, soil rapid measurement, plant culture, sewage treatment, grain storage and measurement of moisture content and temperature of various particles.
