Sensors & transducers
images within the visible spectrum of light. These function similarly to the human eye, detecting and recording visual information in the form of colour images. However, just like the human eye, they struggle with visibility in dusty environments due to reflected light off the dust particles in the air.
That is why these vehicles use radar sensors alongside visible cameras as an additional layer of sensing technology.
Radar sensors emit radio waves, which reflect off objects in the environment and return to the sensor to detect the presence, distance, speed and direction of objects in their vicinity. By analysing the reflected signals, these sensors can operate effectively in situations where visibility is limited. By determining various characteristics of the objects, such as their distance from the sensor, speed of movement and size, radar sensors provide the necessary data to maintain safety and navigation.
SENSOR ADVANCEMENT
Thermal cameras, which detect heat rather than light, enhance vehicle safety by providing reliable vision in various conditions, including dusty environments. These cameras, which are currently found in some luxury vehicles, are increasingly being integrated into the sensor systems of AVs.
Unlike visible cameras that struggle in dust due to light reflection, thermal cameras can "see" equally well in both daylight and complete darkness. They use sensors to detect and measure infrared radiation emitted by objects in their field of view.
The sensor used in thermal cameras is typically a microbolometer, which is sensitive to infrared radiation. When infrared radiation from objects falls onto the microbolometer, it generates an electrical signal that is then processed by the camera's CPU to create a thermal image, which represents the temperature variations across the scene. By detecting the heat emitted by objects, thermal cameras can effectively see past the dust and provide clear images for navigation and obstacle detection. These advancements in sensor technology are helping the industry’s quest for safe and efficient operation across the dustiest of quarries.
In support of this pursuit, suppliers of sensor technology are crucial. One such supplier is Foxmere, an automation parts supplier that can aid the integration of advanced sensor technologies, like thermal cameras and radar sensors, to help autonomous vehicles see past the dust issue in quarrying environments.

DANISENSE PREPARES FOR FUTURE GROWTH
in high-accuracy current sense transducers for demanding applications, has now updated the whole IT infrastructure of its headquarters. The CRM system, the PLM (product lifecycle management) system, the project management and planning system plus the ESG reporting and management software all received major upgrades to ensure Danisense’s IT infrastructure is fully future-proof.
A
fter recently completing the 800 square meter extension of its headquarters in Taastrup, Denmark early in 2024, Danisense, the leader
Remarks Loic Moreau, sales and marketing director at Danisense says: “We have seen some pretty exciting and successful business years in 2022 and 2023 with some big projects turning into real business. That’s why we decided that after completing the extension of our headquarters it was also time to invest in our IT infrastructure to update it and make sure it meets all the latest standards and requirements. Especially the newly updated PLM system is a great help for our growing engineering team to help further develop, design, manufacture, deliver, and service our product portfolio of highly reliable and precise current transducers as fast and effectively as possible.”
Danisense’s engineering team is extensively working on some new additions to the product range which are targeted for launch towards the end of 2024 and early 2025.
