Soil moisture sensors

Two types of soil of soil moisture sensors suitable for irrigation control, tensiometric and volumetric, are shown in this video. Although these types of sensor readings can be related to each other, this relationship is particular to each soil type. Issues of cost and maintenance are briefly discussed and an example an example of how a soil moisture controller work is presented.
