    Greenhouses are becoming more and more popular in the cultivation of fruits and vegetables. The growth of crops is closely related to temperature and humidity. Among the control parameters of greenhouses, the detection and control of temperature and humidity are one of the main parameters. In order to ensure that the ambient temperature in the greenhouse is suitable, temperature sensors are essential! Reliable and stable NTC temperature sensors are used in the greenhouse for temperature monitoring and temperature control in order to control the ambient temperature of the greenhouse and meet the needs of fruit and vegetable production management.

    The optimal temperature for vegetable planting is usually 25-30°C during the day and 15-20°C at night (the temperature difference between day and night is about 10°C), which is more conducive to growth and development; as the ambient temperature changes in spring, summer, autumn and winter, especially In the northern region, the cold environment temperature is low in winter, and vegetables and fruits will freeze to death or stop growing and developing. Therefore, the temperature of the greenhouse must be controlled at 15-20°C at night. However, if only manual intervention is used, it will consume labor. It’s easy to make mistakes; crops need water to grow, so how to irrigate them in facility agriculture without affecting crop growth or wasting water resources is a crucial issue. A soil temperature sensor can be inserted directly into the soil to measure moisture. It is recommended to use a stainless steel, plug-in NTC temperature sensor for measurement. It will not affect the measurement effect if it is buried under the soil for a long time.

    NTC temperature sensor used to detect ambient temperature in greenhouses. Its glass-encapsulated NTC thermistor. The main parameters of the resistor are: R25=50KΩ±1%, B25/50=3950K±1%. When the NTC thermistor is affected by the vegetable greenhouse The resistance value changes when the ambient temperature changes. The resistance value is small when the ambient temperature is high, and the resistance value is large when the temperature is low. The NTC thermistor has the advantages of small size, light weight, stable structure, high precision, fast thermal sensing speed, good stability, high reliability, and high temperature resistance.
