Application of atmospheric pressure sensors in agriculture The application of atmospheric pressure sensors in agriculture is mainly reflected in the following aspects: Precision agricultural management Atmospheric pressure sensors can measure atmospheric pressure and help predict weather changes. Farmers and agricultural managers can use this data to better understand the meteorological conditions of farmland, so as to make more reasonable planting and management decisions and improve agricultural production efficiency. Irrigation system optimization In the intelligent irrigation system, atmospheric pressure sensors are used in conjunction with other types of sensors (such as soil moisture sensors) to achieve on-demand irrigation. When the soil moisture drops below the preset threshold, the system will automatically start the irrigation program, and vice versa, which not only meets the water needs of crops, but also avoids water waste and root diseases caused by over-irrigation. Pest and disease prediction Changes in atmospheric pressure can affect the occurrence of meteorological phenomena and the physiological conditions of crops, and also play an important role in the occurrence of crop pests and diseases and plant adaptation to the environment. By monitoring atmospheric pressure, farmers can predict the occurrence of pests and diseases, take timely prevention and control measures, reduce the use of chemical pesticides, and reduce environmental pollution.

Application scenarios of synchronization mode Common mode: Similar to singing in unison, each sensor is in a state of sending and receiving at the same time. As long as the object to be measured appears in front of this row of sensors, it can be detected, and the response time is fast. Multiple modes: Similar to solo singing, each sensor works in turn. Only when a polling cycle comes, the sensor will have an output, which can accurately determine the specific position of the obstacle relative to the specific sensor. External synchronization: Similar to batch singing, trigger pulses are sent in order through an external controller. For each sensor, while ensuring a safe distance, the sensor can be controlled individually or in batches, combining the respective advantages of common mode/multiple synchronization modes, and flexibly realizing the rapid response of multiple sensors and the location of target objects in complex applications. Other factors affecting the performance of ultrasonic sensors In addition to the crosstalk problem, the performance of ultrasonic sensors is also affected by many factors, including but not limited to the following: Air turbulence Strong air turbulence can have a negative impact on the propagation of sound waves, thereby affecting the measurement results. Sources of air turbulence include wind, compressed air, and cooling fans. In order to minimize the impact of turbulence, physical shielding needs to be provided around the sensor and at the measurement distance. Target materials and surface properties Sound-absorbing materials and materials that reflect sound on the surface are difficult to detect with diffuse ultrasonic sensors, and are more suitable for detection with mirror reflection ultrasonic sensors. Target speed and size Diffuse ultrasonic sensors typically switch at 10Hz or less, so they are not suitable for high-speed applications. The smaller the target, the smaller the detection distance of the ultrasonic sensor needs to be to ensure reliable detection. Target direction For diffuse ultrasonic sensor applications, the sensor face should be parallel to the target. For targets with flat surfaces, a maximum deflection angle of 4° is allowed. Dirty surfaces The sensor of an ultrasonic sensor can remove small amounts of dust and moisture through vibration, but large amounts of dust and moisture will result in poor detection performance. In summary, although ultrasonic sensors may be interfered with in some cases, these problems can be effectively solved by taking appropriate measures and using methods such as synchronization mode to ensure the normal operation of the sensor and the accuracy of the measurement. https://www.renkeer.com/what-is-uv-sensor/
