PS-1 Irrigation Pressure Switch

Simple water pressure sensor

The PS-1 Irrigation Pressure Switch adds irrigation water on/off data into the soil moisture data set. A useful parameter to add to any data set when using soil moisture sensors to monitor irrigation.

The PS-1 registers ON at 5 PSI (±1.0 PSI). Because the sensor must be plumbed into the irrigation line, your data logger should be located where this can be done conveniently and cleanly.
