Engineer/Programmer for Prototype temp/RH logging

PaulS

Thanks for the offer. I will definitely take you up on the offer once I get a system in mind that would work for what I need/want. I will PM you soon.

I love this idea! It's pretty much exactly what I had in mind.

The lack of cables is not a requirement at all, only a convenience. Probe to controller connection being wireless is not essential whatsoever. Controller to PC connection being wireless would be nice.

More on this a little later in the post.

I like the idea of a probe to wireless central base.


Main Requirements:

  • the system must monitor temperature per tank
  • the system must monitor humidity per tank
  • the system must have settings per tank
  • the system must sample temperature every 10 seconds
  • the system must sample humidity every 60 seconds
  • the system must apply a warning when temperature is outside the range [XX..YY]
  • the system must apply a warning when humidity is outside the range [XX..YY]
  • the system must have a local feedback about its working condition (local feedback on control side, much like indication lights on an ethernet connection)
  • the probe must be able to sample data accurately while its electrical components are protected from a high humidity environment (80% RH+)
  • the system (minus PC & any future fan expansion) must be less than 30db loud
  • the system must be easily expandable
    ==> - little difficulty when adding addt'l probes and controllers
  • the system must have a graphical PC interface for customization of data representation and overview of output data
  • the system's data must be easily accessible remotely by persons of little to no computer savvy
    ==> - i.e. hourly tweets or e-mails when function is activated
  • probe and probe connection to controller must be easily installed into tanks that are already inhabited
    ==> - i.e. small probe and probe connector/wire

Since I am a very visual person, here are some more visual aides to go along with requirements and further explanation.

Probe

  • the sensor must be able to take readings and be protected from excess moisture while being in a housing with the smallest footprint feasible.
  • the probe's wire connection to the controller must be as thin as possible
    ==> the midway connector is only needed if the controller's input socket (from probe) is of an unacceptable size
  • it is not necessary for the probe to be wireless
    ===( Any ideas of max probe wire length? )

Controller

  • the input socket from probe to controller must be uniform
    ==> - this way addt'l probes can be added/removed easily and without any tools
    ==> - status indication lights (red/green) for a go/no go on sensor

--Things that would be nice--

  • wireless communication between controller and PC
  • controller mounted small LCD display with 2 button scroll through sensor information

PC Interface

  • wireless/hardline connection from controller
  • remote accessibility of data
    ==> - tweet/sms/email
  • remote repetition of alarm signal
    ==> - audible/tweet/sms/email
  • ability to customize output display
    ==> - custom tank display names, choose which information to display, C or F (maybe K for s&g's)
  • the ability to save a log of sensor readings
  • must be easy to operate for people without extensive computer skills
    ==> - maybe a basic and advanced mode?

It could be a lot fancier than this, but sometimes simple is better.


Well that's it for now.

10,000 thank you's from me yet again!
