GPRS Bill of Materials

This page sums-up the elements needed to build this demo system. Focus was top liability be means of good sensors, minimal power consumption to have an option for solar power feeding and for minimal costs as well. Parts for the whole system sum up to roughly 1400 € (incl. VAT) or 1000 Euro (w/o solar and uv sensor) plus 10 € mobile communication costs per month, plus service charges for Meteoplug serive (starting at 30 € per year).

Hier sind die Bestandteile zum Aufbau des Demo-Systems exemplarisch dargestellt. Der Fokus lag dabei auf hoch-qualitativen Sensoren, geringer Stromaufnahme (um die Option einer Stromversorgung durch Solarpanel zu haben) und natürlich minimalen Kosten. Das Gesamtsystem beläuft sich auf ca. 1400 € (inkl. MwSt) oder 1000 Euro (ohne UV- und Solar-Sensor) plus 10 € monatlich für mobile Kommunikationskosten, plus der Nutzungsgebühren für den Meteoplug-Dienst (ab 30 € pro Jahr).
