Provided are a sensor and a monitoring system, with which the accumulation, on the sensor, of debris of a conveyed substance can be inhibited. This sensor (4) is disposed at a lower side of a return-side section (2a) of a conveyer belt (2), and is characterized by being provided with: a detection unit (40) which detects a body (3) to be detected embedded in the conveyer belt; and a cover (41) which covers at least an upper part of the detection unit. The sensor (4) is further characterized in that the cover is provided with a descending surface (411) which extends continuously towards the lower side, from an uppermost part of the cover, as the descending surface (411) extends outwards in a horizontal direction. |
