Analyzing sensor data on ThingSpeak through the MATLAB Analysis.
显示 更早的评论
Hi, I have a few sensors which send data to the thingspeak platform and the data is being displayed correctly. I am trying to analyze this data in MATLAB to detect a pattern and if possible create an alert. Example if someone walks into a room and creates noise or vibrations within a certain frequency it can detect and create an alert. The data I am getting in MATLAB is in the form of a wave therefore setting parameters or being able to extract only data with a certain frequency and display it as an alert would be ideal. How do I approach this? Sorry, very limited programming skills.

I’m not sure what that plot image demonstrates, however to detect frequencies in a certain range, the best option is n analogue or digital bandpass filter. These are straightforward to design and implement. Calculating the Fourier transform is not necessary.

You can use the Alerts API to create an alert based on a condition you calculate in MATLAB code.After you apply the bandpass filter, call the API to send an email to your MathWorks account address.
