摘要:
A watering warning device (1) for determining watering intervals for at least one plant to be monitored, having at least one moisture content sensor (2), a timer (6) and an evaluation unit (3) is described. The evaluation unit (3) is designed for determining the time (tG) of the next necessary watering operation for the at least one monitored plant in dependence on a characteristic watering curve (S) over time (t), the watering curve (S) being determinable in a self-learning manner in at least one learning phase from a low moisture value (FGN), measured at a watering time, the high moisture value (FGH), measured after completion of the watering operation following the watering time, and the time (tN) until the low moisture value (FGN) is reached, determined with the timer (6) or extrapolated.

摘要:
A weather station with at least one element mounted on bearings on a housing or rack on a vertical axis for alignment with the direction of the wind and with a measuring device, which depending on the angle position of the element aligning in the direction of the wind provides an electrical signal, wherein the measuring device is an opto electric measuring device with at least two light paths. Each of the at least two light paths has its own light-emitting element and which have a common light detector and form a light path configuration, each light path is used to scan a group of markings, which are located around an axis of at least one screen in such a manner that the markings provide a code when scanning that defines the angle area of the position of the element aligning with the direction of the wind. The light-emitting elements determine the angle position of the element aligning with the direction of the wind.
