Seedling cultivation and growth device and NTC temperature sensor

　　Cultivating seedlings in a nursery is called sapling before leaving the nursery. Training seedlings is a crucial step in the process of crop growth. In the field of forestry technology, seedling cultivation is essential, and seedling cultivation in seedling trays is a common method of seedling cultivation.

　　The seedling cultivation and growth device is equipped with a lighting device in the middle of the bottom of the glass cover, which can effectively provide sunlight through multiple internal sun lamps for rapid growth. The monitoring camera set on the right side of the lighting device is convenient for monitoring the real-time growth progress of the seedlings, and the effect is good. By setting a humidity sensor and an NTC temperature sensor on the right side of the seedling cultivation box, the temperature and humidity of the seedling cultivation can be monitored in real-time, By connecting the irrigation channel to the right of the seedling cultivation box, nutrient solution can be injected at any time to improve the growth rate of seedling cultivation and achieve intelligent monitoring.

　　The NTC temperature sensor of the seedling cultivation and growth device uses a high waterproof single ended glass sealed NTC thermistor, packaged with a stainless steel straight tube probe, and welded with high thermal conductivity wires. It has the characteristics of high precision, high sensitivity, high reliability, good stability, and strong waterproofing. It has advantages such as good sealing, resistance to mechanical collision, and strong bending resistance.
