Mike,

 

I'm interested. I would appreciate hearing more about your setup.

Subject: Re: [ecs] Analog readings from Ocelot

 

I believe that the Ocelot analog is an 8-bit value correlating to the
voltage of the input. 

 

0 Volts = 0 and 5 Volts = 255. This means you have to use linear sensor to
be accurate.

 

This is the way that the Stargate works. In their software they have certain
calibration options.

 

I like to use LM334 temperature and an OP-Amp to make the sensors read at
10mv/degree  instead of the standard 20mv/degree F (This cause a minimum of
2 degree F resolution)

 

Many inexpensive sensors come in 0~5 VDC as an input option.

 

I saw your discussion about what system to use on this forum.

 

I don't like using programmable controllers when all I really want are the
inputs and outputs,

 

ECS is surely smarter than any process or programmable control on the market
today, so why pay for something you end up not utilizing to it fullest?

 

If you are interested, I could discuss what I use in more detail.

 

Best regards,

 

Mike Barford

 

PS: the analog reading are integers, but they can manipulated  with floating
point.
