Pulsen tellen/meten

Titel:  Pulsen tellen/meten
Ik ben e.e.a. aan het proberen met de beta versie van de mega nodo en de webapp. Ik heb nu een sensor op mijn draaischijfmeter gemonteerd. Deze heb ik op de IR ontvanger pin van de nodo aangesloten. De sensor geeft iedere rotatie een negatieve pulse. Ik begreep van de NodoWiki pagina dat je gebruik kan maken van de PulseFormula om pulsen te tellen of de tijd tussen de pulsen te berekenen.

Klopt het dat ik het als volgt moet uitvoeren?
Mijn meter geeft 600 pulsen per kWh.

Meten verbruik per dag:
Formule1: Variable = ( Pulse / 600 ) * 1 + 0
Dus invoeren: PulseFormula Count, 1, 600, 1, 0

Meten verbruik op dit moment:
Formule2: Variable = ( 3600 / Pulse ) * 1 + 0
Dus invoeren: PulseFormula Time, 2, 3600, 1, 0

En hoe krijg ik vervolgens de waardes naar de webapp gestuurd?

Alvast bedankt voor de reactie's.

Dit wil ik dus ook met de nodo doen wat voor sensor heb je hier voor gebruik?. Kan ik ook met 1 nodo zowel de elektriciteit en gas uitlezen?

@h143: De sensor die ik hiervoor gebruik is de http://www.dealextreme.com/p/intelligen ... sor-121352
Ik heb nog niet gekeken of deze ook op mijn gas meter e.d. werkt.

@mdegraag: Bedankt voor de informatie. Ik kan nu iig weer even verder. Ga het in ieder geval proberen voor het totaal verbruik.

@Sjoerdp zoals je zegt is nu eigenlijk het actuele verbruik het verbruik tussen de 2 laatste pulsen van de afgelopen minuut. Eigenlijk zou je eigenlijk voor het actuele verbruik een berekening maken van hoeveel pulsen er de afgelopen minuut zijn geweest en afhankelijk daarvan de waarde iedere minuut naar de webapp sturen.
