Flow Sensor Upload to Xively using a GSM Shield

Hey Guys,

Looking at uploading a flow water sensor every 5minutes or so to Xively.com

The flow sensor works by a simple rotating wheel that pulses a hall effect sensor. According to the site, "By reading these pulses and implementing a little math, we can read the liquids flow rate accurate to within 3%."

The code for the HallSensor can be found at http://www.seeedstudio.com/wiki/G3/4_Water_Flow_sensor

^The problem with the above code provided by SeedStudio is that this program stores the data as a float and to upload to Xively.com, one needs to send the site a String.

I wrote some different code that creates a new String (for the flowsensor) which does upload the flow sensor but without the decimal.

If someone could find a way to fix my code to send the actual correct value and/or record continuous values during the downtime of the 5 minutes (sample every 1min) then send all that data you would make me the happiest! :smiley:

I have attached my code if you would like to view it.

Thanks,
Andy

No you don't. You might be seeing somebody playing fast and loose with language, but you send a datastream which is made of floats.
