Temperature and humidity are key environmental factors that determine crop growth. They affect seed germination, growth rate, flowering and fruiting time and, ultimately, yield and quality. This is because the same crop will have different requirements for temperature and humidity throughout its life cycle.
Therefore, when the temperature and humidity are out of the appropriate range, it will seriously affect the agricultural production process and results. Therefore, real-time monitoring and control of temperature and humidity is very important to optimize the growing environment and improve agricultural efficiency.
（1）High temperatures may cause crops to flower and bear fruit earlier, reducing yields. Low temperatures can slow growth.
（2）Excessive humidity can aggravate crop pests and diseases. Excessive dryness affects soil nutrients.
（3）Each growth stage is sensitive to temperature changes and requires different management.
Installation of temperature and humidity sensors in agricultural facilities such as greenhouses and warehouses. This is used to monitor changes in environmental parameters in real time. Because the sensor can be connected to the data acquisition module. So through the environmental control system or agricultural management software, can receive real-time data. To achieve precise monitoring and regulation of temperature and humidity facilities within the effect. Special attention should be paid to the distribution of sensors need to be scientifically arranged.
For open crop planting areas, the need to establish environmental monitoring stations. And in different areas and altitude deployment of temperature and humidity sensors. Because of this, it is possible to carry out a wide range of environmental monitoring. The monitoring stations transmit temperature and humidity data to a centralized system via a wired or wireless network. By analyzing the results of the data, agricultural cultivation managers and experts are able to provide a reference for temperature and humidity changes in large cultivation areas.
Satellite remote sensing can acquire meteorological and environmental data on a large regional or even national scale. Surface temperature and humidity can be indirectly measured by analyzing cloud maps and infrared spectral images. This provides macro support for regional decision-making on agricultural production and early warning of disasters.
Temperature and humidity monitoring is an important support for intelligent facility agriculture. It can realize the precise control of environmental process and optimize crop growth. It can also provide basic data for intelligentization. Real-time temperature and humidity can help agricultural planting managers to determine whether the parameters are in the best range.
As well as timely arrangement of closed-loop control, it can also effectively establish growth and pest models. Therefore, it is of great significance to the efficient production of agriculture.
（1）By monitoring different areas of the facility, it is possible to determine whether the temperature and humidity are uniform and adjust them.
（2）Closed-loop control of ventilation, heating and cooling, humidification, etc. can be performed based on temperature and humidity data.
（3）Long-term temperature and humidity data can be used to model crop growth and guide planting strategies.
（4）Pests and diseases can also be modeled for control and prediction.
（5）Temperature and humidity data can also be used to evaluate the performance of environmental control systems.
