Sunload sensor for automotive vehicles

A dual sunload sensor to sense the intensity and directionality of solar radiative power entering the cabin of a vehicle through a windshield, said sensor comprising:

• a housing;
• a substrate bearing only two light sensitive semiconductor elements thereon housed in said housing;
• two optical lenses, one lens being located above one of said only two light sensitive semiconductor elements, the other lens being located over the other one of said only two light sensitive semiconductor elements, each of said optical lenses refracting light towards a the respective corresponding light sensitive semiconductor element;
• and
• an optically opaque wall separating said two optical lenses lying in a vertical plane along a longitudinal axis of the vehicle.
