At present, greenhouses have great advantages in vegetable cultivation; in the vegetable market, we often see various vegetables in different seasons, most of which are grown in greenhouses; vegetables are usually grown at a temperature of 25-30°C during the day and 15°C at night. The temperature range of -20°C (the temperature difference between day and night is about 10°C is the best) is more conducive to growth; the temperature changes throughout the year, especially in the north, the cold temperature in winter is low, and the vegetables will freeze to death or stop growing, so it is necessary to increase the greenhouse temperature. The temperature is controlled at about 15-20 ℃ at night, but if it is only controlled manually, it will consume human resources and prone to errors; in order to ensure that the temperature in the greenhouse is suitable, high-reliability NTC thermistors will be used in the greenhouse to make temperature automatic controllers. Temperature monitoring and temperature control to control the greenhouse temperature and meet the needs of production management.

The NTC thermistor used in the greenhouse temperature controller has a long service life. The resistance value changes when the ambient temperature changes, the resistance value is small when the temperature is high, and the resistance value is large when the temperature is low. The NTC thermistor has the characteristics of small size, light weight, firm structure, high precision, fast thermal induction speed, good stability, high reliability and high temperature resistance.
