Kijk eens bij dealextreme, sku 158589.
Google die chip maar even... Volgens mij is deze geschikt voor 230V AC.
Je ziet ze vaak voor lagere stroom, maar deze kan 30A aan.
Kwestie van in serie zetten met de verbruiker.
Ik heb er al eentje besteld... :D

Even een opmerking, voordat jullie massaal gaan bestellen.
Deze sensor geeft de actuele stroomsterkte weer, een momentopname dus.
Je zult zelf een slimme manier moeten bedenken om periodiek een gemiddelde stroomsterkte te berekenen, om daaruit een vermogensafname te geven.
Dus bijvoorbeeld: elke seconde meten en opslaan, eens per 5 minuten het gemiddelde berekenen en dat doorgeven aan de webapp. Daar kun je met een eenvoudige formule het afgenomen vermogen over die 5 minuten berekenen en in een grafiek zetten.
Zodra ik de sensor binnen heb ga ik ermee aan de slag.

Een LDR hoort thuis op een analoge poort. Ik zou geen reden kunnen bedenken waarom dat niet betrouwbaar is.

Kan ik deze meter ook uitlezen?

ja, alsbij het laatste cijfer i.p.v. de 7 een "metalen vlakje zit. CNY70 ervoor, aansluiten aan arduino.

Hoi John,

Gevonden, de nul is een metalen plaatje.

Als het maar een metalen plaatje is......
