Chattering noise coming from under the car,located on the exhaust

(1994 Volvo 940)
The noise is constant, it's not noticeable when driving but when parked and running it can, I'm not sure what it may be, never had anything like that before. The part of thee exhaust that the noise is located on, has what looks like a sensor ? Let me know what you think?
