An electronic device is for monitoring the visible spectrum of a specified sample with agile monitoring techniques. The device may seek to decouple the sensor from static measurements and allow for dynamic measurements in systems where the response is not wide sense stationary, allowing the end user to aggregate multiple data points or moments in summarizing the health of a larger system. In aquacultures, the device may be capable of functioning as a floating buoy where a chemical sensor with a color response can note readings at multiple points within a stream or water body.
