Series Probes have been discontinued. Use the
VH400 probes instead.
The VG400 high frequency series soil moisture
sensors are low power, very affordable, durable, and provide an
excelent feedback to
sprinkler control systems. They put out a voltage of 0 to 3V
related to the water content of the soil. They can also be used
as water level sensors.
