l want to develop a device that can detect animal action which denote a sign of illnesses and alert the owner for emergency check up of such animal.which sensor that are very sensitive for the work.
The accelerometer of most modern transmitters can provide accurate enough data to determine such behavior in comparisons with previous periods. The problem is that for such a study it will be necessary to continuously take a large number of points and this will drain the battery very quickly.
@Hristo Peshev thank you for your contribution but we can employ UpS to the accelerometer if that is the case.
Yes, accelerometry doesn't drain the battery very much. The issue is transmitting the data, I've been working with LoRa tags and large volumes of data can take a long time to transmit. for GSM it's less of an issue but then you run into the power issue. The solution is to use some kind of trigger threshold and I will be submitting a paper for publication soon about the results from my trials using the LoRa tags to detect collisions. We did trial them on vultures but I think we set the trigger threshold too low so the tags just filled up with 2 second brsts of 25Hz ACC data......
For your use case, you might be better having something on the server end analysing the data for unusual values of ACC in the X, Y or Z axis which would suggest that the bird is at an unusual angle for an extended period. this wouldn't need high intensity monitoring and it is something we often do manually with the hourly "Status" messages from our tags which containa single X, Y and Z ACC reading.
Thanks, @Jethro George for your contribution, please you can forward the work via [email protected]. Thank.
