Can cygnus be used to trigger a change in Context Broker?

I am developing a service agent where I want to know when the values of sensor are changed. Instead of developing an automatic http request in my service to query context broker (each 15 mins or so) I want to know if I can configure cygnus to notify me of these changes?

Im doing this because I want to put the data coming from my sensors in an algorithm that detects certain trends.

Thank you, I hope my question is clear enough.

If you are not an experienced user of fiware technologies please ignore this question.

Probably it is better that you subscribe and end point (integrated with your service) to orion so your service is notified when the sensor value change.

Do you really need to use Cygnus?
