With the development of agricultural modernization, the degree of agricultural automation is constantly increasing, and the application of multifunctional calibrators in the field of agricultural automation is also becoming more and more extensive.
In greenhouse cultivation, temperature and humidity sensors, light sensors, etc. are used to monitor and control the greenhouse environment. The growth of crops is extremely sensitive to environmental conditions, and suitable temperature, humidity, and light intensity are the keys to ensuring high - yield and high - quality crops. In a certain modern vegetable greenhouse, technicians use multifunctional calibrators to calibrate the temperature and humidity sensors. The multifunctional calibrator generates a series of standard temperature and humidity values, inputs these standard values into the temperature and humidity sensors, and compares the differences between the measurement results of the sensors and the standard values. Through calibration, it is ensured that the temperature and humidity sensors can accurately measure the actual temperature and humidity in the greenhouse. The calibrated temperature and humidity sensors can provide accurate data for the automatic control system of the greenhouse, making the temperature and humidity control in the greenhouse more precise. When the temperature in the greenhouse is too high, the automatic control system will start ventilation equipment and cooling devices; when the humidity is insufficient, it will start humidifying equipment. Such precise environmental control has significantly improved the yield and quality of vegetables. Vegetables grow in a suitable environment, with a reduced incidence of diseases and pests, and improved taste and nutritional value, providing higher - quality agricultural products for the market.
In the agricultural irrigation system, flow sensors are used to control the irrigation water volume. Water resources are important resources for agricultural production, and the rational utilization of water resources is crucial for improving the efficiency and sustainability of agricultural production. When the multifunctional calibrator calibrates the flow sensors, it uses standard flow devices to generate water flows with different flow rates, passes these water flows through the flow sensors, and compares the differences between the measurement results of the sensors and the actual flow values. Through calibration, it is ensured that the flow sensors can accurately measure the irrigation water volume. The calibrated flow sensors can precisely control the water supply volume of the irrigation system according to the water requirements of crops. For example, in the dry season, according to the growth stages and water - demand characteristics of different crops, the irrigation water volume is precisely adjusted, avoiding the waste of water resources while meeting the growth needs of crops. This precise irrigation not only improves the utilization efficiency of water resources but also reduces the production cost of agriculture and promotes the sustainable development of agriculture.
