EC-5 miniature soilmoisture sensor
TheEC-5 sensor can measure the volumetric moisture content (soil moisture) of theculture medium and soil. Due to the high-frequency characteristics of EC-5, itgreatly reduces the influence of electrical conductivity (EC) and soil textureon its reading, which is applicable to all soil types; The high measurementfrequency also improves the accuracy and range of the sensor.
