Hi all, I need to know how to calibrate The Sentek Soil Moisture Sensors by comparing sensor readings with actual soil water content values over a range of soil moisture contents.
The best way to calibrate the sensor is by obtaining a core soil sample from the point that you where are going to install the sensor. Then, in the laboratory, you are able to determine soil water content of the sample by implementing conventional techniques (drying the sample). The first measurement of your sensor can be compared with the soil water content that you determine in the laboratory.
