Rain Sensor Circuit

Rain Sensor Circuit

DESCRIPTION

The auto wiper system adjusts the wiper speed to the optimum speed based on the amount of rain. The rain sensor mounted on the windshield detects rainfall. This system operates when the windshield wiper switch is set to AUTO. The rain sensor sensitivity can be adjusted with the rain sensor adjusting switch. Signals are sent to the front light ECU from the windshield wiper switch through the CAN line, and from the rain sensor through the LIN line. Based on these signals, the front light ECU operates the wiper and determines its operation speed.
