How can i put the generated Sensor Data from my Android Matlab App to thingspeak?

I generated acceleration Data with my Android Matlab App and now i would like to connect it with thingspeak, how is that possible?

From the MATLAB app, you can use the thingSpeakWrite function to write data to ThingSpeak. Note that the time resolution of data on ThingSpeak is 1 second. What is the resolution your data is sampled at? If is is higher than 1s, can you do some local processing of the data before you write the data to ThingSpeak?

My resolution so far was 10 Hz but i changed it now to 1 Hz. Is it necessary to do some local processing then?

Where can i find the thingspeakwirte function?

Hi Luis Spechtenhauser,

You can use Simulink Support Package for Android Devices to convert a Simulink Model to Android Application. You can achieve writing to acceleration data to ThingSpeak using standalone app.

Acceleration data can be obtained using Accelerometer block and write to ThingSpeak using ThingSpeak Write block. Create the Simulink model and deploy on your Android device
