will seeedstudio current sensor work on 1 wire?

[mtmtntop]

i need a current sensor to monitor a radon fan.  i have an existing 1 wire network.  If i cut off the plug on this device:

and wire into the correct pins, will it be readable by the 1 wire network?  all i need is an on/off condition.  thanks

Depends on what you are using to read the data.
 
I using test the device first with the Maxim 1-wire viewer application to look.
 
In the wintel world I use a small xAP "widget" which works fine.  There are also plenty of 1-wire applications today for the linux world that work well.
 
I do not see where in the specfications where it states that its a 1-wire device? 
 
I have two water meters with NC/NO switches for counting, these two meters connect to a dual 1-wire counter.  I use the same setup for my legacy 1-wire Dallas rain tipping bucket and lightning sensor,  
 
I just set the variable for the 1-wire counter to the description of what it is that its counting (gallons, number of tips equal to like .01 inches of water, lighting per minute stuff)
 
Have a quick read here on 1-wire devices.
 
It is guaged at the Midon stuff but offers a nicer overview of methodologies and topologies of 1-wire stuff in general.

you are right, it does not say it is a 1 wire device, and i really didn't know what t actually makes a device work on  a 1 wire network.  thus my question.  Thanks for that reference material from midon.  I had never come across that before.  I do know there is at least 1 manufacturer making a current sensor for 1 wire, but its quite pricey.

You can make it work if you connect it to a Hobby Boards dual counter like this one:

Here is a temperature and current sensor:

Here I utilized three Temp0X devices and 3 serial 9097 devices with multiple layered hub and spoke networks inside and outside of the house.

It does not have a pulsed output so why would you connect it to a counter?  You need to connect it to an A/D converter.

You are right az1324.  What would you suggest?

Pete/all,
 
Connect the sensor to a 1W a/d converter such as a DS2438 or DS2450 and connect that device to the 1W network.  You'll need a burden resistor sized to the current of interest and likely some filtering/rectification depending on what you want to do with the measurement.

P.S. Pete: thanks for the callout!
