Description: Onboard sensors are devices installed in drones that allow for data collection during flight. These sensors can measure a variety of parameters, such as temperature, humidity, atmospheric pressure, air quality, and more. Their primary function is to provide real-time information that can be used for various applications, from environmental monitoring to precision agriculture. Onboard sensors are crucial for the effective operation of drones, as they enable informed decision-making based on accurate data. Additionally, these devices can be of different types, including optical, thermal, and ultrasonic sensors, each designed to meet specific measurement requirements. The integration of these sensors into drones has transformed data collection and analysis, facilitating tasks that previously required considerable human effort or the use of more expensive and less accessible equipment. In summary, onboard sensors are essential components that expand the capabilities of drones, allowing their use across a wide range of industries and applications.
