Sein Vorteil ist die Kommunikation \u00fcber I\u00b2C. Er wird nicht wie andere Sensoren \u00fcber einen ADC am Microcontroller selbst abgefragt. Der Preis liegt so zwischen 3 und 4\u20ac bei den Amazonen und noch billiger beim schnellen Ali. Auch k\u00f6nnen bis zu 4 Sensoren (Einstellung der Adresse beachten) parallel betrieben werden. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"verwandte-beitraege\"><span class=\"ez-toc-section\"
