Manual Fan Control Temperature System with Arduino Uno WiFi

This project shows you how to build a temperature alert system that will allow you to manually trigger a fan to turn on or off from hyper links.

NOTE:

This project can be a bit “quirky” as written. Auto refresh does not work well on Google Chrome. This should be taken purely as a learning experiment, and not something to be copy/pasted to a real environment.

Functional Parts in the Project:

nice! maybe you can auto stop after it reaches your desired temperature as well!

at 4:10 you may be missing a decoupling capacitor. (Usually 100nF between VCC and GND as near the sensor as possible.) Check the datasheet of the sensor! It is often requirement for stability...

Edit: Yup that is the case! Page 10, under Fig 24. "Note the 0.1 μF bypass capacitor on the input. This capacitor should be a ceramic type, have very short leads (surface-mount is preferable), and be located as close as possible in physical proximity to the temperature sensor supply pin."

Da, remember me, the generation z, it seems like you deleted your silicon dojo channel so that you can have access to one of youtube's algorithim, well im back in the game

34 likes for the Arduino crowd in only 15 hours....; that's like going viral! :)

Have it update every minute unless temperature has exceeded safe range

13:10...if the if else is just to print out the first line. Why not just print it out first. and the rest that comes out anyway. Just have to type it once.


if (temperatureF >= highTemp) {
client.print("<h1 style=\"color:red; font-size:400px; margin-bottom: 10px;\">");

} else if (temperatureF < highTemp && temperatureF >= goodTemp) {
client.print("<h1 style=\"color:yellow; font-size:400px; margin-bottom: 10px;\">");

} else {
client.print("<h1 style=\"color:green; font-size:400px; margin-bottom: 10px;\">");

}
client.print(temperatureF);
client.println("</h1>");
client.println("<a href=\"/?fanon\"\">Turn On Fan</a>");
client.println("<br />");
client.println("<br />");
client.println("<a href=\"/?fanoff\"\">Turn Off Fan</a><br />");

Dont know a lot about programming, but that's one reason im tempted to get an auduino would be fun to play with.

What happened to the fourms on the eli site being free? Not that im complaining you gotta make the money.

But just a typo:

"Please Note that the $1 per month level receives the same benefits as $50. At this point it is simply how much you would like to contribute to this effort."

There doesn't appear to be a 1$ per month level anymore just a 5$ a month or 60 a year(which i mean value wise why pay yearly?)

Eli, would you consider working on some of the more complex temperature sensors? I was thinking checking out this sensor amplifier (below), but I didn't really understand the way they were building their code. Anyway, I was thinking of using it to measure my grill and oven temperatures and thought it would be more fun if I created something with I could use around the house.
