Sensing / Logging/ Communicating

Thu Feb 25, 2016 12:30 pm

Hi Everyone,

I'm really excited to get started on my first Raspberry Pi project.

I understand that this may not be the absolute correct topic, but this project involves many different factors. Sensing underpins it all so I decided to post it here.

To start, I have the A+ 256mb model. This is all the equipment I have right now (barring a screen and keyboard and mouse, I have that).

This is what I want to do:

I want to program this device, in Python, to be able to do the following:

- Detect a certain frequency of sound (I must be able to adjust this frequency if needed).

- Record how long that frequency is present (the sound will be coming from an external source. I.E. A machine.)

- Log that time (accurate to 1/10 of a second).

- Communicate that log, in real time or perhaps half hourly, to me (via email or something similar). The device will not be near me, but connected to wifi.

Please feel free to ask as many questions as you'd like to help clarify.

Luke.

If you would use a Pi2 (or Pi3) I would suggest to use Wolfram Mathematica for frequency analysis.
I have no idea if an A+ would be sufficient to run it .

Do you know any programming language ?

Yes, Python and a little bit of html.

I sugget using Python , it's free and you can code on your faster
Laptop/Desktop and transfer the code to your Pi and it should
run without any/minimal changes.
