Sunlight sensors detect the amount of solar radiation to improve air conditioning efficiency and provide a higher comfort level for driver and passengers in vehicles with separate cooling zones. Hamamatsu's S8369 sensor uses a photodiode to measure the infrared heat load of the sun's rays and a special cap shape to achieve a wide-angle of directivity. The one-piece plastic package design integrates the sensor assembly and connector in a single housing. The unit has a spectral response from 320 to 1100 nm. To meet passenger compartment requirements, the sensor has an operating temperature of -30 to +80C. Custom versions address different specifications, including multiple zones, and added functionality. For more information on Hamamatsu's sunlight sensor go to: http://rbi.ims.ca/4914-501
A new method of modeling how they are created with chemical vapor deposition (CVD) could reduce the cost of carbon nanostructures used for for research and commercial applications, including advanced sensors and batteries.
BMW has already incorporated more than 10,000 3D-printed parts in the Rolls-Royce Phantom and intends to expand the use of 3D printing in its cars even more in the future. Meanwhile, Daimler has started using additive manufacturing for producing spare parts in Mercedes-Benz Trucks.
