For the last few years, more and more sensors
have been hitting the market and for good reason. A sensor is like a thermostat for
your landscape. It collects data on site and tells your irrigation controller whether irrigation
is needed. Sensors allow your controller to accurately and automatically adjust your irrigation
schedule to save water by up to 60%. There are two main types of sensors, weather sensors
and soil moisture sensors. Weather sensors are typically installed on
a roof or fence and adjust irrigation schedules to weather and seasonal conditions. They measure
rainfall, temperature, solar radiation and humidity. They can also help prevent irrigation
during a freeze or rainstorm so the plants get just the right amount of water.
Soil moisture sensors are installed in the ground and detect moisture levels to determine
how much water is needed at the root level. Some sensors are sold with an irrigation controller
and some are sold as add-ons for an existing controller. When installing sensors, choosing
the right location will be important. Keep them away from downspouts and drains and be
sure to mark where they’re located for maintenance. What’s better, a weather sensor or soil moisture
sensor? It all depends on your specific site needs. Some irrigation controllers allow combining
both the soil moisture sensor and weather sensor for additional water savings.
