Soil Moisture-Based Irrigation Systems
Irrigation Sensor Placement
This video shows proper installation of a soil moisture sensor for irrigation control. The soil moisture sensors should be placed in the root zone of irrigated plants. It is important to place the sensor so that there is no air gap around the sensor. The soil should be packed firmly around the sensor.
