Application of sensors in agricultural machinery and equipment

In agricultural machinery manufacturers, photoelectric sensors, pressure sensors and ultrasonic sensors are used in different scenarios to improve the automation level and operating efficiency of equipment. The following are their main application directions:

1. Photoelectric sensors

● Crop detection and positioning: used to detect the position, size and shape of crops to help machinery perform precise sowing, fertilization or harvesting operations.

● Material detection: In feed delivery, seed sorting and other links, photoelectric sensors can be used to detect the flow of materials to ensure the normal operation of equipment.

● Light intensity monitoring: Some photoelectric sensors can be used to measure the intensity of ambient light to help optimize crop growth conditions or adjust equipment operation time.

● Color recognition: used to identify crops or materials of different colors, such as distinguishing between ripe and unripe fruits, or detecting the difference between weeds and crops.

2. Pressure sensors

● Hydraulic system monitoring: In the hydraulic system of agricultural machinery, pressure sensors are used to monitor oil pressure to ensure the normal operation of the hydraulic system and the stability of the equipment.

● Soil pressure monitoring: used to measure the compaction of the soil or the tillage depth to help adjust the working state of plows or other tillage tools to avoid over-tillage.

● Material pressure monitoring: In fertilizer, seed or other material delivery systems, pressure sensors can be used to detect the pressure in pipes or containers to ensure the stability and safety of material delivery.

● Mechanical load monitoring: Used to monitor the load of mechanical parts to prevent overload and damage to equipment.

3. Ultrasonic sensor

● Crop height measurement: Ultrasonic sensors can be used to measure the height of crops to help adjust the working height of harvesters or mowers to avoid damaging crops or missing immature parts.

● Obstacle detection and avoidance: In autonomous or semi-autonomous agricultural machinery, ultrasonic sensors can be used to detect surrounding obstacles to ensure safe operation of equipment.

● Material level detection: In storage bins or hoppers, ultrasonic sensors can measure the level of materials to help monitor and manage the storage of materials.

● Distance measurement: Used to measure the distance between machinery and crops, soil or other objects, and between soil or other objects, to help equipment operate accurately, such as adjusting the spraying height or depth of spraying equipment.

Summary

Photoelectric sensors, pressure sensors and ultrasonic sensors play an important role in agricultural machinery manufacturers, used to detect, monitor and control a variety of parameters. Their combined use can improve the automation level, operation accuracy and production efficiency of agricultural machinery, while reducing the need for human intervention and providing technical support for the intelligent development of modern agriculture.
