Software apps and online services
Today I looked at an example from the Particle Maker Kit and modified it slightly for my needs. The core components are still preserved, but I do not let the temperature record in an Excel spreadsheet through Google, but I also use the ITFFF service supplemented by Blynk to measure the measured values at a cozy barbecue evening and when the core temperature is reached of the grilled food according to the need for action (take the meat away from the heat source).
Take a look to the example video and build the circuit at first. You need a resistor between data and VCC. I use 3 crocodile clips around the connection of the temperature sensor not directly with the breadboard loosely, but to have more fixed.
Remember to add the correct library into the sketch: I used the Particle WebIDE and included this:
#include <blynk.h> #include <OneWire.h>
Use your Blynk remaining Energy to create 4 widgets: 2 displays (actual temperature at the moment and the wishes threshold for your meat), 1 slider to change the threshold, and 1 graph to see what happened over time.
Don't forget to change the authenticity code of Blynk.
Here is what you need to do: 1. Download Blynk app here 2. Scan this QR code 3. Enjoy my app!
After the flashes of the Sketches, the first measurements can be made: a cup of coffee or tea can also be served. Also gladly the baby bottle or the desired bathtub temperature. Simply set the required signaling temperature using the slider. In my example, it was about the Sissle Zone at one of my friends who invited to a piece of steak at 55 degrees core temperature for grilling. As it turned out I would endanger the sensor in this heat (hotter than 980 degree) and we have to leave it to try.
If the current temperature, which is checked every 2 seconds, reaches the set threshold value, a trigger fires via IFTTT. In my case this is an e-mail, but it can also be an SMS or something else.
As an example of the brewing of a pot of tea, I can imagine the following extension well: with the hot water of the automatically disconnecting water cooker at 100 degrees (which can be followed very well with this sketch), the prepared teapot is poured over with the filled loose tea. However, there is still a timer (often 8 minutes draw time) or reaching a drinking temperature in the range of 40 degrees. Who dares to enlarge?
