The system includes a CMOS sensor having an array of pixels that captures images in an area of interest. The system monitors the average pixel value for the array to define a first state. If the average pixel value changes beyond a defined threshold, the system defines a second state. For each change in state, a signal is generated. In one embodiment, the optical sensor is used with a meter having a dial with an indicator. The optical sensor generates a signal each time the indicator passes through the area of interest to allow for the remote monitoring of a consumable commodity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical reading system and method of operation","description":"An optical sensor for detecting motion or movement in an area of interest and a method of operation is provided.
