Data Logger & Software combo needed

Hi Cabe,

Currently we are working in a datalogging system with RS232, ZigBee, 868Mhz or GRPS connectivity. The logging board has following features:

- 2MByte of data storage.

- Real time clock

- 4 analog input channels for current sensing, temperature measurement, 0..20mV / 0..1V / 0..10V input voltages

- RS232 usable as eiher communication device or as sensor input device

- Dedicated sensor input for digital relative humidity and tempearture measurement

- The logger board is designed to be batterypowered

- The logger can be placed in a network with up to 1024 nodes

- We also have gateways to LAN / WiFi

Software uses a simple command set to

- configure the sensors

- control the measurement cycles

- manage stored data

- control network parameters of the device

Currently we are also workin on an PC based application for data acquisition.

Product will be available in the late summer this year. We are also interested in OEM clients (even for small amounts)

We can do custom modifications to the sensor board. Feel free to contact us.

Kris,

Can you post more information on your logger? What is the brand, where can I see it, etc?

Cabe

Hi Cabe,

The logger is still under development, which is our own brand. Where s-in the phase of beta-testing right now. Commercial documentation will ony be available as from september. So will be our website, where more information will be posted. The current version of our website www.signum-engineering.be is in dutch only and contains no information about the products currently under construction. (it's simply too soon for that).  The software protocol is also still under development, but is very much the same if you would like to connect over TCP/IP (through our Sensor-to-LAN interface), external RF device or the RS232.

On server side, we are working on a database application to hold and visualize the captured data of  all sensors. This package will be on sale as well, probably by the end of the year

The logger uses 4 channel of 16 bit analog to digital conversion, with a conversion rate of max. 400 Hz

There is high precission current source output ranging from 10µA to 1mA

A digital counter input can sense pulses up to 20kHz pulses

The digital sensor interface is mainly designed to interface with our relative humidity and temperature sensor.

The logger comes either as barebone PCB or as built-in in an IP67 housing (64x96x40mm) with an external 868 antenna. Target pricing for the barebone logger will be less than 200€ in small volumes.

Kris,

If you want, I could use your logger in my design. I could act as a test subject perhaps?

What I have are 3 or more 4-20mA or 0-10V analog signal coming out of my monitoring hardware.

I need the following:

- At least 12 bit accuracy

- To be able to display the data in real time on a laptop screen in real time

- The ability to save the charts

- A spreadsheet of the data

- Possibly a way to directly print from the logging software

Let me know if you can do all this.

You could try these guys, http://www.edacelectronics.com/

they have a variety of loggers, even some that will advise you via cell ph text messages and some that will log onto a web site.

Cheers

Warren,

They have interesting options. Good to know some advanced loggers are out there.

However, I need something simple like this, http://www.picotech.com/precision-data-acquisition.html and the software http://www.picotech.com/data-logging-software.html

I would go with them, but the software is a bit buggy and does not work the way I want it to.

I can use all the help I can get.

Have you seen this http://www.home.agilent.com/agilent/product.jspx?nid=-35204.536881544.00&cc=US&lc=eng

Does a nice job of monitoring up to 60 channels.

Paul,

Looks good. But for my application, I need something smaller. A LCD is not necessary for my device, since it will interface with a PC.

I saw these usb loggers from advantech. Never used them but the price is pretty good. Not sure of what software is available or comes with the unit.

Roban,

I like those Avantech loggers. However, the support software is not as full featured as I need.
