The invention relates to a detection method for forecasting fruit maturity based on fruit skin color and environmental temperature. According to the method, an intelligent color sensing module and an integrated temperature sensor based on the chip of a wireless singlechip CC2430 are installed in a fruit tree for comprehensive detection and judge of the fruit maturity. Onsite measuring sensor networking is carried out through a Zigbee module and monitoring data low power consumption wireless transmission is realized. A frequency signal outputted from the color sensor is subjected to signal conditioning, digitization and parameter correction so as to obtain a RGB parameter of the fruit surface color. An analog signal outputted from the temperature sensor undergoes AD conversion and filtering correction and then is used as a factor for judging the fruit maturing trend. The above parameters undergo multi-sensor data fusion and analysis and then the fruit maturity can be evaluated and simultaneously the fruit maturing speed can be forecasted. The method can be used for remote and nondestructive detection of fruit maturity. Therefore, managers can master fruit harvest time flexibly, thus minimizing economic loss of orchard workers.
