Hola estoy iniciandome con arduino, y me dieron un trabajo para programar un sensor de corriente unsando:

Mi problema es sobre la programación, osea que comandos utilizar para la programación.
Tal sensor se encuentra en la tercera parte de la sgte página:
http://www.electronicaestudio.com/sensores.htm
Les agradecería mucho su apoyo, además de seguir desarrollando, pués a final mi objetivo sera desarrollar un calibrador usando arduino.
Sorry, I didn't understand your language. I think there is another arduino forum that can understand you.
El sensor se alimenta con 5V (del propio Arduino) y la corriente a medir se hace pasar por las clemas azules.
En el VOUT del sensor habrá una tensión (posiblemente 2,5 voltios)
Cuando pasa corriente por la clemas, esa tensión varia (posiblemente en ese sensor 100mV por cada Amperio) y es lo que tendrás que medir en una entrada analógica del Arduino.

Hello, I'm starting with arduino and gave me a job to set a sensor that measure AC power using:

This sensor is located in the third part on the next page:

I would appreciate your support, because in the end I want to develop a gauge using arduino.

It appears this device will output between .5 volts, and 4.5 volts, depending on the current sensed.
I think I would use a volt meter to verify that, before I hooked it to an arduino analog input tho.
Then I would include some over voltage protection to the input pin.
Do you have the device on hand now? Do you have a volt meter?
Did that make sense?
Yes I have. what I want is to write a program that put: current, power, volt, using this sensor, my problem is the program because I'm recently learning C languaje.
To calibrate the sensor . I'm trying to use this configuration:

As I want to in the end me sense the most accurate possible.

Gracias, ya pude implementarlo, lo que aún no logré el implementar los comandos o en sí el mismo programa para que mida la corriente y me ponga I=25 A por ejemplo, ademas que estoy tratando de buscar la forma de poder calibrar el sensor para obtener la mejor lectura Posible, uso un modelo parecido a este solo q en lugar de la celda puse el sensor, no s si este en lo correcto, encendio el led, aun no se si esté calibrado XD XD XD
Este es el link: http://arduino.cc/en/Tutorial/Calibration
Gracias.
RESPONDAN PRONTO....

@jeisonhdtv, maybe you can't speak english, (surly I can't speak spanish). I can't understand what you say. I am trying to help here, but it is frustrating to try to read what I can't understand. Please, lets keep this english version to english. Thanks.

Update: looks like I made the mistake. I am sorry. Seems like I got into the wrong language forum some how.
