Welcome to Monitor. This month we've replaced the 
Excel Corner with an OpenOffice Corner, giving tips 
on getting live data from instruments and devices into 
the Open Office Calc spreadsheet. We're also offering 
subscribers 27% off pH monitoring over USB.

For more data acquisition news and tips follow us on 
Twitter - @DataAcquisition.

We had some problems with our on-line store last month - 
my apologies if you were affected. Everything is now back 
to normal at https://www.windmillsoft.com/, and we
have a new special offer on pH measurement.

I hope you enjoy this issue, but should you wish

27% Off pH Monitoring via USB
________________________________________________________

Measuring pH via pH via the computer's USB port
Use your PC to monitor 12 pH 
electrodes or probes with 
the - now reduced - Microlink 
751-pH package. Connect up 
to eight 751-pH units to one PC 
to monitor up to 96 pH probes. Previously available for £1095, 
we are pleased to offer it to you now for just £795.

Included in the price is Windmill data acquisition software, 
which makes setup and data logging very easy.  Our modular 
suite of software also provides charting and alarm indication, 
lets you control other equipment and can send data to Excel 
and other software in real-time.

The Microlink 751-pH uses an integrating analogue-to-digital 
converter which reduces internal noise, and a differential 
amplifier which helps remove external noise. The Microlink 
also lets you monitor temperature, flow, level, 
gas concentration, resistance and other parameters.

OpenOffice Corner: Getting Live Data into OpenOffice
________________________________________________________

OpenOffice is similar to the Microsoft Office suite of 
programs, but OpenOffice is free! It includes a 
spreadsheet program called Calc.  Today I'll explain how 
to get live data into OpenOffice's Calc.

Windmill programs communicate with your instruments and 
devices and can send the data directly to OpenOffice.  
If you don't have a copy of Windmill, subscribers can download 
a free trial that will collect data from instruments 
connected over TCP/IP (Ethernet and Internet) RS232, 
RS422, RS484 and Modbus.

To get the live data into OpenOffice you just enter an 
"array formula" there. An array formula returns multiple 
results, rather than just one, so you can see readings 
from all your data channels. You enter an array formula 
by pressing the Ctrl+Shift+Enter keys.

Using OpenOffice with DDE Panel
===============================
To get live data from DDE Panel into OpenOffice

1. Start DDE Panel and connect your data channels. 

2. In OpenOffice's Calc, select a row of cells large 
   enough to hold all the channels. 
	 
3. Enter this array formula: 
   =DDE("WINDMILL";"data";"AllChannels")
   don't forget to press the Ctrl+Shift+Enter keys to 
   tell Calc that it is an array formula.

4. The formulas is displayed as 
   {=DDE("WINDMILL";"data";"AllChannels")} 
   and new data appears in Open Office whenever the 
   DDE Panel updates.

To change the update rate, go to DDE Panel and change the 
Refresh Rate there.

Changing the data collection rate with DDE Panel 

Another way to enter the data is

1. In DDE Panel, click the Copy to Clipboard button and 
   select Copy All Channels. 

2. In OpenOffice, choose Paste Special from the Edit menu 
   and select DDE Link. 

3. The array formula given above is automatically entered 
   and the data appears. 

Using OpenOffice with Logger
===============================
Windmill Logger collects readings from instruments and 
devices, and saves it in a series of text files. You can 
simultaneously collect data with Logger and show it 
in OpenOffice.

1. Start collecting data with Windmill Logger.

2. In OpenOffice's Calc, select a row of cells large enough 
   to hold all the instrument channels connected to Logger

3. Enter this array formula:
   =DDE("Logger";"data";"AllChannels") 
   don't forget to press the Ctrl+Shift+Enter keys to tell 
   Calc that it is an array formula.

Using OpenOffice with several copies of Logger
=================================================
You can run more than once copy of Logger at a time. 
This is useful, for instance, if you want to log data 
from different channels at different rates. In this 
case you need to change the new  Logger's DDE service name. 
From the Logger File menu select DDE and type in a new 
name. In your formula, change "Logger" to your new name.

When earthquakes occur, the energy harvested from the vibrations activates the wireless transceiver to transmit the data packets which contain the sensor's identifier. The greater the vibrations, the greater the energy harvested and the more packets that are sent.
