Its for an entrepreneurial class, more or less a thesis capstone type of class. We have to develop our own idea for a product and produce a full business plan. And it wouldn't have to be a phone btw, could be email, or just an alarm. The options for this are kinda endless haha.As a person who doesn't own and has never owned a cell phone, I'd have to say no for myself. But I know quite a bit of people are all for that stuff, and could be useful for shop owners and people with larger stashes.
What class is this for?
Well, I kinda gotta be a bit hush hush for IP reasons. But I have a material, a polymer, that will swell in the presence of water or moisture and is semi sticky when wet. Attached to this will be metal plates and in between these will be a metal pin to make a contact switch. The idea is that if the moisture isn't just right, the contact pin will either separate or make contact with the plates and the circuit will either break or be completed and you can see where this goes lol.Post some more info. about your project.
You might be better off using a semiconductor...Well, I kinda gotta be a bit hush hush for IP reasons.

2nd. What OP describes sounds like an analog hygro hooked up to a wire. There's no way to calibrate effectively, plus using a mechanical switch like that only notifies whether rh is greater than whatever maximum you set based on the wire position. Even if you have a second contact to act as the minimum you're still in unknown territory when it's in between.You might be better off using a semiconductor...
So, I was thinking of attaching a digital meter to this thing, and then just having my gel be the moisture emitter. I feel like this would be a better use of my device. And the advantage is that when it gets low on water, it will make contact with a pin between to plates and set off an alarm telling you you need to resoak the gel. Does this sound like a better idea jacob? It would also have like RFID technology or something to transmit to a device what the moisture level is and such. Similar to how you've done it.2nd.

Don't try to reinvent the wheel. Stick to something that's lab tested and proven. Anyone who is serious about humidity monitoring and willing dropping to drop cash on a hygro will only accept digital. http://www.sensirion.com/en/01_humidity_sensors/00_humidity_sensors.htm
That's almost been done! Someone built a device that sends the readings to Twitter every hour iircMaybe its a WiFi Iphone App hygrometer with updates every 30 minutes. If its not, that idea now belongs to me. Pay me!
Yes, .jacob did it, and he is working with me as well. Twitter is a good idea but I'm thinking of posting it to a program or app on your phone or computer.That's almost been done! Someone built a device that sends the readings to Twitter every hour iirc
I would like to have one that notified me on a bracelet, like the Medic Alert.Yes, .jacob did it, and he is working with me as well. Twitter is a good idea but I'm thinking of posting it to a program or app on your phone or computer.
HAHA, I'll see what I can do for ya!I would like to have one that notified me on a bracelet, like the Medic Alert.
"Your humidity's fallen, and it can't get up".
I have a patent on it, I just have to build the entire device. You guys will be the first to see it though!Just build it, patent it, and pass some out around here and before you know it you'll be on a beach drinkin pina coladas.
