It is determined by special sensors, dry bud temperature, ambient humidity and iteration. An example of this is the Rika sensor R330. For a wet bud temperature Tw = 0\u2070 C -0.5\u2070 C, the ambient temperature under different humidity conditions is within 1\u2070 C -3\u2070 C.<\/p>\n<p>The irrigation is stopped when Tw = 1.5\u2070 C is reached.<\/p>\n<p>The sensor should be installed in an area away from the building At a height of 1.5 -2 m. At the same time, we must avoid sprinkling. This is possible with the SDI 12 or Agrobee \u2013 L loggers, which were described here. The sensor readings are transmitted via radio connection to Agronik, which automatically activates the sprinkling system at Tw = 0\u2070 C -0.5\u2070 C and turns it off at Tw = 1.5\u2070 C. Human duty and intervention are not required.<\/p>\n<p><img decoding=\"async\" class=\"lazyload alignnone wp-image-3398\"
