The solar sensor, also called a pyranometer, allows irrigation based on the amount of light. It is a method that is more adapted to the true reality of plants. It offers less handling and maintenance than the tensiometers. It is also possible to manage the irrigation of as many greenhouses as you want for the whole farm at the same time, which saves costs in the long run.
