Multiple Sensor Network

XBee & XBee Gateway NDS-based Gateways

Hi,

I want to build a sensor network ie monitor the temp of about 15 water tanks, I have xbee series 2 radios but what would be the easiest way to get all of the data ie temperatures on a computer screen ? , any info appreciated.

Thanks

What kind of sensors are you working with? Are they analog or do they have a UART?

Hi, the sensors will just be analoge temp sensors connected to an adc channel on the zigbee, so in effect I will have 15 zigbee radios all sending the adc info.

Then it is really nothing more than you needing to write an application that can both read and pars the ADC data from the API frames coming fem the COM port that the XBee module is connected to.

Hi, yes I was wondering what the gateways were for, are they a web server that gets your readings onto a computer network ?

Also can the 15 xbee routers talk to 1 xbee set up as a coordinator…

Thanks

They are a device that allows you to collect the data from the XBee modules. Then send that data to a server via an internet connection of some sort such as a WIFI, Ethernet or Cellular.

Yes, you can have more than 15 routers talking to one Coordinator. It just really is a function of the overall throughput available.

Hi, do you know if there is info somewhere about receiving multiple data frames ?

Thanks
