Beitrag zum Kalenderwettbewerb<\/a> 2015 von Leander Hackmann:<\/h2>\n

Jeder hat Topfpflanzen. Sie versch\u00f6nern unseren Alltag, ben\u00f6tigen jedoch auch h\u00e4ufig unsere Aufmerksamkeit in Form von Pflege. Um den besten Standort herauszufinden und das regelm\u00e4\u00dfige Giessen nicht zu vergessen, habe ich folgende Anwendung mit dem Iot-Board entworfen und umgesetzt: ein Datenlogger f\u00fcr Licht und Feuchtigkeit.<\/p>\n

Das Programm misst zur vollen und halben Stunde (Zeit wird aus dem Internet bezogen) Helligkeit und Feuchtigkeit, um diese dann in zwei Graphen auf Thingspeak.com zu schreiben. Bei zu trockener Erde (der Wert \u201ethreshold\u201c muss individuell angepasst werden, bei mir lag der Wert f\u00fcr feuchte Erde bei rund 400) leuchtet dann eine rote LED und ansonsten eine gr\u00fcne. Die Stromzufuhr f\u00fcr den Feuchtigkeitssensor (ein Spannungsteiler), wird nur periodisch eingeschaltet, um Elektrolyse in der Erde zu vermeiden. Au\u00dferdem m\u00fcssen Graphitelektroden (z.B. Bleistiftminen) verwendet werden, um die Pflanze nicht durch Ionen einer Elektrolyse zu vergiften (besonders bei Kupfer besteht Gefahr).<\/p>\n
Auf Knopfdruck wird in beide Graphen ein Nullwert geschrieben, beispielsweise um Anfang und Ende einer Messung auf dem Graphen festzuhalten. W\u00e4hrend der \u00dcbermittlung von Daten und bei Messungen wird zur Kontrolle die gelbe LED eingeschaltet.<\/p>\n
\"sch-001\"<\/a>Das Bild zeigt einen experimentellen Aufbau (es wurden nur andersfarbige LEDs mit eingebautem Vorwiderstand verwendet, der Aufbau ist aber nach der Fritzing-Abbildung mit Bauteilen aus den Kalendern realisierbar).<\/p>\n
