WHY IT MAKES SENSE TO USE HIGH COST SENSORS TO DO LOW COST SENSOR RESEARCH [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022 The question is highly topical in the world that is aiming to acclaim more efficiency through an omnipresence of sensors. The implication of the omnipresence of sensors clearly is that most of these sensors will be of the low-cost type. Hence, there is a

Low cost infrared and near infrared sensors for UAVs [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014 Thermal remote sensing has a wide range of applications, though the extent of its use is inhibited by cost. Robotic and computer components are now widely available to consumers on a scale that makes thermal data a readily accessible resource.
