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
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
