Looking to build wifi alarm to monitor chest freezer temperature

General

Hello. I’m new to Spark and to programming, but think that this could be a perfect solution to my needs.

I have a chest freezer which occasionally gives out, without warning. I’d like to build a unit with a simple temperature probe and configure an alarm to send me an email or SMS message if the probe detects that the temperature has risen above a certain level.

While there are commercial chest freezer temperature alarms available on Amazon, none of the reviews convinces me that they would be as reliable as a Spark project could be.

Has anyone already done this, or have any suggestions?

Thanks!

@carloswlkr, it would be easy to configure a Spark with a DS18b20 (like this one) one-wire temperature sensor (there is a library for that!) and use the Spark.variable() function to make the temperature available to the cloud. Then you can use IFTTT to create a rule that would send an SMS or email or tweet or whatever based on a threshold temperature. Easy peasy. The hardest part will be to ask to be put on the Spark IFTTT beta test list :smile:

Thank you @peekay123! I will look into that.

Honestly why do you need IFTTT? A simple $4 thermistor and the Spark Core as it is will work wonders. Combine it with ubidots and you have monitoring with email / text message alerts in under 1 hour :slight_smile:

Me to this is an awesome community. I am not a spark guru but I work in a mechanical field and am dangerous as a front end developer :slight_smile:

I built a spark powered temperature monitor/control for my “keezer” which is basically a kegerator made from a chest freezer. I wrote an android app to monitor and set the temperature. Spark makes it really simple. :slight_smile:
