Sun angle sensor simplifies integration
Design How-To  
7/3/2008   Post a comment
Sensors for the measurement of the angle of incident light are required for many applications in vehicles, with air conditioning control being the most important. Available systems, however, can only be accommodated with great difficulty due to limited available space. In addition, they represent a source of optical irritation. The single-chip ASIC-based solution described avoids all these problems.
