1. Date Judgment Fruit maturity requires a certain accumulated temperature, and the number of days after pollination is judged to be mature.
2. Morphological characteristics When the fruit matures, the peel is shiny, hard and smooth, the pattern color is deep and clear, the fruit pedestal and the flower mark are inwardly slightly sunken, the melon stem is distorted and aged, the base hair is detached and the fruit is near the tendril withered. .
3, after listening to sound to identify melon sound voiced.
4, hand method to identify, ripe melon touch, the edge of the bump is obvious, there is a sense of outstanding, hand pressure umbilical elasticity, one hand care melon, the other hand when the palm of the hand has a fluctuating feeling.
When harvesting, 15-20 cm long melons are harvested, preferably in the morning.
Short range distance sensors from JRT combine highly precise measurement results with quick and reliable response. Short distance sensor module use single-transmit and single-receive measurement technology and can be used to measure a distance or monitor the slow moving objects. For the laser pointer distance measure, also called optical range sensor, can measure legth, width, depth. Laser rangefinder transducer with rxtx has been widely used to industries.
