Long distance LiDAR sensor series are particularly easy to communication thanks to their fixed connector, which can be plugged it up and off by yourself. Voltage is wider from 8v before to 36v. Low power consumption feature makes it beceome a very competitive, high performance-price ratio, long range Laser Distance Sensor.

The standard sample seed is a physical standard for indoor seed purity testing. If a well-proven standard sample with consistent morphological characteristics and strong viability is not properly preserved, it will lead to distortion of the standard sample, reduced viability, and thus to seed purity. Inspection brings difficulties. Pre-storage Selection and Treatment of Standard Seeds According to the characteristics of different crop varieties, dry seeds with the botany characteristics, typical genetic traits, full grain, healthy maturity, and vigor of the varieties are selected as the standard, and then the standard seeds are selected. Clean, remove impurities, imperfect grains and seeds with virus, and dry the seeds or dried naturally by artificial low temperature (below 40°C) to control the moisture content of the standard seeds within the safe water content, thereby prolonging the storage life and storage. Methods include: Drying The clean and dry standard seeds are placed in paper bags or cloth bags and placed in brown glass bottles or iron boxes. A layer of anhydrous calcium chloride or silica gel is placed on the bottom of the container and is equivalent to the amount of seeds. Lime and other desiccants, or equivalent to the number of seeds 2 to 3 times the dry grass ash can also be stamped and sealed, kept in a cool, dry place, drying each year, and replace the desiccant, using the method can be marked Samples are safely stored for 2 to 3 years or more. Simple sealed method: The dry standard seeds are first wrapped in toilet paper or cloth bag, and then put into pots or brown glass bottles, then covered and sealed, set at low temperature, dry, ventilated place (or 4 °C ~ 6 °C refrigerator) Can be stored for a long time. Hanging method The dry standard seeds are put into a black double bag and hanged in the sample room or standard sample cabinet to keep the room or cabinet dry, cool, ventilated, free from direct sunlight and pest free. The seeds are safely stored for 3 to 5 years. Ears, pods, and fruits are used to carry air-dried standard seeds with spikes, ribbons, and fruit in nylon gauze bags, suspended in a standard sample room, and stored in a cool, ventilated, cool, dark place. This method is commonly used for the storage of crop seed samples such as corn, wheat, rapeseed, soybeans, and peanuts. The method can fully ripen the seeds, and can protect their morphological characteristics will not change, while allowing the ears to fully dry, to avoid the impact of environmental temperature and humidity mutations on the seed, generally safe storage for more than 2 years. The seed samples of different crop types have different storage methods, and should be scientifically selected during storage so that the stored standard seeds can maintain their morphological characteristics and viability for as long as possible to ensure their use value.
