What do you need Phidgets to do for you?

few sensors:

Postby zero0ne » Sat Mar 15, 2008 4:11 am

a fully functional PPM sensor (or EC sensor)
(by full I mean including the probe, as its hard to find JUST the PPM probe)

Co2 Sensor for the 8/8/8 kit (I found some real cheap ones online; links at home, maybe you guys could buy them in bulk an whip em up with a analog plug, etc...)

Dissolved Oxygen sensor (doubt youll do this, as the cheapest sensors I have found of these are close to a thousand bucks!)

Could you buy some perilistatic pumps from some chinese manufacturer; you could sell just the pumps AND you could maybe make a usb board for controlling them

all i have for now!

cheers,

Thanks a lot,

can't but they are typical sensors you would get from a chinese manuf. company.

this is the company that most test labs get theirs from (least school wise)
http://www.vernier.com/probes/index.html

Co2, there was some company online that was making one that can output to 0-5v for a 0-10k range for like 100 bucks... cant remember the site though....


maybe this thread should be moved to the sensors thread?
(tough I do touch on pumps )

Dissolved O2 has been considered, CO2 is an interesting idea.

Not going to lie, a really hardened 4-20ma ratiometric device would be the best thing sensor wise, as it would allow an assortment of sensors to be used with the device.

(unless that is basically what the phidget PH sensor is... not sure how your typical BNC pH sensor outputs)

One other idea is a infrared temp sensor, so that you can just point it at what you want measured and bam!

It was mentioned in a few other threads, a 4-20ma current sensor IS coming. It's in the production queue. And yes, it is a very good device to have.

I think that IR temp sensor was being looked into, but I don't know if or what was ever done.

Awesome guys, I see you just released the 4-20ma sensors!

Thanks!

CO2 sensor:

Code: Select all

I plug mine ( K-30 10,000ppm CO2 Sensor) into the 1019 - PhidgetInterfaceKit 8/8/8 w/6 Port Hub.

Works perfectly!

Hi Glenvn,

Are you still using this? I have a k-30 as well, and I'm trying to use it with a 1018 8/8/8 but I'm new to phidgets and I'm not getting a reading from the k30. It may be that I've got it wired wrong, but I'm wondering if you have a picture or wiring diagram you would be willing to share.

Thanks for any help you can offer!
