Sensor Technology
Sensor technology obtains information about an object without directly contacting it. In an agricultural environment, information about the soil or crop is usually gathered from a plane-based, satellite-based, or agricultural equipment-based sensing device. Data collected can range from a simple color photograph to the crop’s emission of electromagnetic energy. Sensor data can provide farmers real-time information regarding their crop condition, allowing them to respond and make corrective or other management decisions to maximize crop production. Data can be collected for an entire field as compared to traditional scouting methods which only provides single point or partial field coverage during the growing season. Data collection over multiple dates during the season allows farmers to monitor trends in crop progression. Examples of sensor technology used in agriculture include on-the-go sensors, aerial photographs, near-infrared (NIR) date, and thermal imagery. Integrating remotely sensed data into a GIS can reveal information about soil characteristics and general crop health that can be a valuable tool for site-specific management.
