Volg dit topic al even met interesse, maar mis net even de basis opzet om verder te kunnen.

Heeft iemand wellicht een voorbeeld stukje script voor plugin 28 om een (kWh) meter met pulsen uit te lezen ? Voorbeelden die ik op het forum vind zijn veelal nog op de oude Pulse meting gebaseerd.

Opzet is om op wired-in 1 (a8) van de Mega een DIN Rail kWh meter met s0 uitgang te meten en zichtbaar te maken via de webapp.

Daarna wil ik nog aan de slag met een dubbele TCRT5000 print om zowel het vooruit als achteruit (zonnepanelen) draaien van een Ferrarismeter te loggen.

Alvast hartelijk dank !

En ik zou nog graag willen weten wat de grootorde van frequentie is van de pulsen die van gas/water/elek-meter komen.
Uit de beschrijving van de plugins begrijp ik dat er op micro seconden nauwkeurig gemeten kan worden, dat is naar beneden afgerond 100KHz. Maar als pulsen worden aan geboden in een frequentie van 1 Hz of lager, kan ik die Arduino nog heel veel andere dingen laten doen.

Heeft iemand wellicht een eerste stukje voorbeeld code beschikbaar voor pulse meting ?
Doel is het registreren van een kWh meter en later ook de gas- en watermeter.

Alvast hartelijk dank !
