SIGNALING THE STATE OF A GROWTH SUBSTRATE FOR A PLANT
The invention relates to a method for signaling the state of a growth substrate (5) for a plant (7), having the following steps: - measuring a physical growth substrate (5) variable (79) which depends on the state (3) of the growth substrate (5) using a measuring device (99), - specifying a first th...

Summary: | The invention relates to a method for signaling the state of a growth substrate (5) for a plant (7), having the following steps: - measuring a physical growth substrate (5) variable (79) which depends on the state (3) of the growth substrate (5) using a measuring device (99), - specifying a first threshold (123) for the physical variable (79), - reproducing a sequence of differentiable optically perceivable flashing signals (21) as long as the physical variable (79) exceeds the threshold (123), wherein in order to allow a state signaling which is as readily perceivable and energy-saving as possible, - the physical variable (79) is continually measured using at least one photocell (27) and without a battery, - reproducing a second optically perceivable flashing signal (23) which can be differentiated from a first flashing signal (21) as long as the physical variable (79) does not exceed the first threshold (123), - and permanently reproducing at least the first and/or the second flashing signal (21, 23). |
