Choose Best Soil Moisture Sensors – More Water Saving
An automatic irrigation system is mostly convenient every time. However, when significant rainfall occurs, farmers will see the need of a sensor that knows when to interrupt their watering system. In some countries, there are laws that require the presence of a working sensor in farms and gardens which are equipped with automatic irrigation systems. At the time being, there are two choices of sensors available for farmers: rain sensors and soil moisture sensors.
Generally speaking, both types of sensors have their own pros and cons that worth considering when you need to choose one. Rain sensors are cheaper and easier to install. It costs you only $30-$85 for a working rain sensor, but the charge will be over $100 for a unit of soil moisture one. Installing a rain sensor only means finding a vertical flat surface in your garden with open sky above so the device can have an access to the rainfall. Soil moisture sensors installation, however, consists of more stages, surely involving getting your hand dirty.
Still, after taking many surveys and research, we come to a conclusion that soil moisture sensors are more beneficial than rain ones. Some reasons below may explain the statement.
NO recalibration required
Rain sensors may cost you less, but they require regular recalibration. Otherwise, they won’t working accurately and false shut downs will occur to your sprinkler system. You will find a rain sensor beneficial at first, but will the price justify the need of checking and re-checking?
STEADY working quality
A rain sensor’s capacity will gradually decrease over time. You have to change your rain sensor’s disk expanding material regularly to maintain its best performance. The burden will be lifted completely off your shoulder if you choose a soil moisture sensor for your garden.
MORE water saved
Expensive as they may be, soil moisture sensors can save much more of your water consumption than rain sensors do. Many surveys done by multiple groups of researchers show that soil moisture sensors can save twice as much as rain sensors do during the same time, on the same land and under the same weather conditions.
After seeing all the reasons above, you must realize the better features of soil moisture sensors over old-fashioned, less beneficial rain sensors. Therefore, we’d like to recommend two outstanding devices for your choice.
