Re: [Emc-users] Ethernet data collector?

There are libraries for both SPI and I2C. It can also read 0-5V inputs, though limited to 8-bit resolution which ay or may not be an issue. Ultimately it depends on the sensor though. If you check the forums on arduino.cc you should be able to find examples. Sent from my iPhone On Mar 11, 201

Re: [Emc-users] Ethernet data collector?

I'd do this with an Arduino which can speak serial over USB and is accessible to people with no embedded experience. You will need other sensors for measuring things but there is a ton of information out there about that. You can also interface with EMC pretty easily. Sent from my iPhone On

Jon, it looks like there are "ANALOG INPUT PCI CARDS" for PCs that are available. They should fit the bill, no? Are there linux drivers for those? i On Thu, Mar 10, 2011 at 8:57 PM, Jon Elson wrote: > Igor Chudov wrote: > > I want to collect a few analog data pieces, like 5-6 current values (

Re: [Emc-users] Ethernet data collector?

First question is what speed do you need from measurement to delivery in the pc? A range within Mikroseconds would be much more complex than within milliseconds. If a few milliseconds is fast enough than an ad converter with multiplexer and a little microcontroller could do the work and deliver it

I want to collect a few analog data pieces, like 5-6 current values (AC and DC), some temperatures, voltages etc. is there some thing that lets me do it and disseminate it somehow to my Linux PC, via ethernet or USB or whatever. --
