Abstract: An optical sensor may include a housing, a printed circuit board, an optical emitter, and an optical detector. The housing can define a channel configured to receive a transparent tubing line through which fluid can flow during operation. The housing can have multiple optical pathways, including a primary optical pathway transecting the channel, a light emission optical pathway, and a light detection optical pathway. The optical emitter and optical detector can each be mounted on the printed circuit board. Further, the housing may be positioned on the printed circuit board with the optical emitter aligned to emit light into the light emission optical pathway and the optical detector aligned to receive light from the light detection optical pathway.

Abstract: A cockroach monitor includes a monitoring chamber with one or more openings to allow cockroaches to enter. A light is emitted from a light emitter into the monitoring chamber and received by a photoelectric transducer for detecting cockroaches by analyzing the received light for obstruction in the path of the light. In various embodiments, a board having a sticky surface can be attached to a ceiling of the monitoring chamber to capture cockroaches by their backs. In various embodiment, the light emitter and the photoelectric transducer are arranged in the cockroach monitor for the photoelectric transducer to receive the emitted light directly form the light emitter (without reflection) or to receive the emitted light as reflected from a surface.
