Sensors used in Drone Technology
With advancements in drone technology, Altitude Sensor for Drones are installed for data collection. This collected data can be used for various purposes. These drones detect changes in physical, electrical, or other quantities and as an acknowledgment of the change in the quantity, produce an output. Drones can maneuver better with the help of the Altitude Sensor for Drones as they help detect changes in their surroundings and also help in the collection of important data about the object under inspection.
Types of Altitude Sensor for Drones:
Different types of sensors can be used in a drone for recording different types of changes and for also collecting a variety of information.
(1) Distance and Speed Sensors: This type of Altitude Sensor for Drones can be used to measure the distance between the drone and another object or detect the speed of the drone, with absolutely zero physical contact with the object. This can be achieved in different ways, such as:
- Solar-pulse distance sensing: In order to estimate the distance of an object from the drone, Ultrasonic waves are sent from the Altitude Sensor for Drones in form of the pulse width of the waves. But this method can be irregular if too much noise is present in the environment as it makes use of sound waves.
- Light-pulse distance sensing: It is a method of direct measurement. It makes use of a laser diode that emits extremely short, but powerful light pulses that are reflected by the object and then with the help of a light-sensitive receiver, it is again detected. It is in accuracy, precision, and noise immunity where its advantage lies.
- Magnetic-field change sensing: This Altitude Sensor for Drones can be helpful in determining the position of the drone and can also be used to sense the presence of magnetic fields and objects.
You can avoid collisions, navigation, etc. with the help of these sensors.
(2) Thermal and Infrared Sensors: Depending upon the precision of the sensors, the potential uses of infrared sensors are vast, especially in cameras. Some of its main applications include surveillance, pipeline inspection, search and rescue, forest and crop health, etc. Although infrared is not visible to the human eyes, one can feel it as radiated heat when its intensity is high. Thus, areas of high temperature can be detected by thermal cameras. Overheating sections of electrical equipment in various devices like substations and switch gears can be revealed by it. These sections can be detected from a distance with the help of these drones and thus increasing the safety of the human personnel. Altitude Sensor for Drones can also be used for night vision and surveillance.
(3) Image Sensors: The constitution of an image can be detected and conveyed by an image sensor. This is achieved by the conversion of the variable attenuation of light waves into signals. The sensors are installed in the cameras which are carried by the drones to create a digital image of the picture taken by the drone. They find applications in several areas like thermography, sensor arrays for X-rays, the creation of multi spectral images, and other highly sensitive arrays for astronomy.
(4) Chemical Sensors: This is a self-contained device. This type of Altitude Sensor for Drones can be attached to a drone which can provide relevant information about the chemical composition of any environment. The analytic molecules present inside the device selectively interact with the molecules present in the environment whenever there is a change in the chemical composition of the environment. When a change occurs, the signals can be sent with the help of a transducer that is connected to the device.
SPH Engineering – All you need to know
A globally recognized provider of UgCS, SPH Engineering is a UAV mission planning and flight control software solution. Professional surveyors and drone pilots worldwide make use of this constantly evolving software particularly in areas of mining, environmental, archaeological, engineering, and biological surveys. In fact, the UgCS educational program, which is another aspect of it, aims to support universities with an efficient and safe tool to test ingenious ideas around inspections and surveying using drones.
Drone Show software, which is another technology from SPH Engineering, is used to coordinate and manage the flight of dozens or even hundreds of drones. Another business line of SPH Engineering is the UgCs Integrated Systems. This enables the advanced technological integration between various sensors, drones, the UgCS software, and the UgCS Sky Hub Hardware. Integrated systems have been developed by the company for their clients, some of which make use of nonstandard sensors like metal detectors, gas detectors, ground penetrating radars, and magnetometers unlike the more traditional camera or LiDAR.
