Evening all,
I am looking for an engineer who can produce a *simple* data logging circuit for me. I can give you more details on request, just looking to see if someone is interested in a little paying project? The quick specification is....
Four universal channels
8bit or better Channels to accept 0-5V and Thermistors (or some other temperature sensors)
5V Excitation which turns on and off before taking a reading allowing a quick "warm up" time for powering transducers. Storage of 4000+ readings per channel or better Time Stamp along with data readings RS232 Interface Programmable logging rates from 2hours A digital channel for pulse counting would also be a nice addition Battery power (lithium)
Production cost is a major issue, isn't it always!, I need to keep this as low as possible!
Thank you for your time looking at this post. You can reply here or on my email below...
