Design of environmental adaptive gray tracking sensor

Abstract： In this paper, a new gray-scale tracking sensor is designed to solve the problem that the gray-scale tracking sensor cannot automatically adjust the reference voltage when the ambient light changes. The sensor combines a microprocessor with a traditional gray-scale tracking sensor circuit. The microprocessor performs fusion calculation on the detection voltage signals collected by the multi-channel traditional grayscale sensor circuit to obtain the optimal reference voltage under the ambient light to solve the problem that the traditional grayscale tracking sensor reference voltage cannot adapt to the ambient light and there is the problem of tracking misjudgment. Experiments show that the sensor design scheme improves the tracking accuracy of the gray-scale tracking sensor and the environmental adaptability of the traditional gray-scale tracking sensor.
