    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium that automatically performs actions in an aquaculture environment based on light sensed by underwater cameras. One of the methods includes obtaining images of a surface of water captured by a camera that faces upwards from a depth towards the surface of the water within an enclosure that encloses aquatic livestock. An ambient light metric is determined at the depth from the images of the surface of the water. A determination is made as to whether the camera satisfies one or more depth criteria. Based on determining that the depth of the camera satisfies the one or more depth criteria, it is determined that, based on the ambient light metric at the depth, one or more action criteria are satisfied, then initiating performance of an action to be performed for the aquatic livestock.

    Abstract: A sensor circuit comprising a sensor input includes a delta-sigma analogue to digital converter. The delta-sigma analogue to digital converter includes a switched capacitor, a common mode voltage source, a reference voltage source, and a switch network. The switch network, in a first clock phase, connects the switched capacitor to charge it to either a sum or difference voltage, and in a second clock phase connects the switched capacitor to transfer charge into a summing junction. A controller controls the switch network responsive to a comparator output to selectively connect the switched capacitor to one of the common mode voltage and the reference voltage in the first clock phase. Implementations of the sensor circuit transfer charge every clock cycle and have low noise and high sensitivity.

    Abstract: Provided are a light intensity detection circuit, a light intensity detection method and an light intensity detection apparatus. The light intensity detection circuit includes a photoelectric conversion sub-circuit, a source follower sub-circuit, a reset sub-circuit, a read sub-circuit and a sense sub-circuit. The photoelectric conversion sub-circuit generates a corresponding electrical signal according to an incident light signal, and outputs it to a first node; the source follower sub-circuit generates a corresponding voltage signal or current signal according to the electrical signal of the first node and outputs it to a second node; the read sub-circuit reads the voltage signal or current signal of the second node to determine an incident light intensity; the reset sub-circuit provides a voltage at a offset voltage terminal to the first node.

    Abstract: A method to measure and report electromagnetic radiation power includes receiving electromagnetic radiation and generating an electrical signal having a magnitude based on the power of the electromagnetic radiation. An adjustable gain may be applied to the electrical signal to generate an amplified electrical signal that may be sampled to generate a digital sample. The adjustable gain may be controlled based on the value of the digital sample and the digital sample may be associated with a gain value. One or more calibration factors may be selected based on the gain value associated with the digital sample and the selected calibration factor(s) may be used to calculate the power of the electromagnetic radiation.
