Single Solar
Sensor
Applications
The single solar sensor is mounted on
the dash panel near the front window. It
uses one photodiode cell to measure the
intensity of solar radiation and give
electric information which is proportional
to the calorific power and representative
for the intensity of that. And then feeds it
back to the automatic temperature
control (ATC) unit of the vehicle’s air
conditioning system. The air temperature
is automatically adjusted up or down,
depending upon the amount of light
entering into the vehicle.
Features
Fast response time
Easy to install
Linear response to sun light intensity
Narrow signal tolerance
