Den Chip gibt es mit einer kleinen Schaltung fertig auf Platine. Es gibt diese in verschiedenen Varianten abh\u00e4ngig von der maximal zu messenden Stromst\u00e4rke (5,20,30 Ampere). Die gemessene Stromst\u00e4rke wird in eine proportionale Spannung umgewandelt und an einem Pin ausgegeben. Dieser kann \u00fcber einen analogen Port gelesen werden.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Was ist ein Preview?<\/strong> Hier zeige ich kurz Hardware, die ich entdeckt, aber noch nicht genauer angeschaut habe.
