Hey guys i need some help!

I want to monitor three thermometers using the arduino sending the information to a database.

When brewing beer there are three pots that you have to monitor their temp.

I want to log each batch and plot the results from a MYSQL database.

I need suggestions for thermometers, lcd screen, and code and methods to save to a database.

Where do i start?



Where do i start?

With small sketches that test a single feature.

Write one to read from a sensor. Write one to read from multiple sensors. Write one to write to the LCD. Write one to send random values to the serial port, for a PC application to read and store in the database.

When each part works independently, merge them together into one sketch.
The art of getting good answers lies in asking good questions.


Tip for the temperature sensor: DS18B20 are very accurate and fast enough for the task. Besides multiple of them can be controlled over same set of wires (one-wire protocol) . There exist an excellent lib for these sensors with examples . Think that is a good starter - http://milesburton.com/index.php/Dallas_Temperature_Control_Library

Arduino is not capable to write directly to a MYSQL DB so you have to make a small PC app that capture the serial output of the arduino (e.g. <temp1, temp2, temp3 newline> and insert in the DB (with a timestamp I guess).

Take also some time reading the tutorials - http://arduino.cc/en/Tutorial/HomePage - very informative

Hopes this helps getting started.
