Smart irrigation controllers with watering strategies based on evapotranspiration (ET) have been around since the late 1990s. These controllers attempt to calculate the loss of moisture from the root zone and adjust the watering schedule accordingly.
Have you ever wondered how ET-based watering stacks up against soil moisture sensor-based watering?
Wouldn’t it be better to schedule watering based on an actual measurement of moisture in the root zone instead of an estimate? Early soil moisture sensors earned a poor reputation for dependability and reliability, but the design and technology of Baseline’s soil moisture sensors make them the most advanced sensors in today’s market.
