Weather conditions e.g. rain, detecting device for car, has electrical sensor for detecting conditions, and electricity generation unit for generating electricity with portion of heat flow by thermoelectric effect for supplying sensor

摘要

The device has an electrical sensor (20) e.g. rain or brightness sensor, for detecting weather conditions e.g. rain, and an electricity generation unit (10) for generating electricity with a portion of heat flow (70) by thermoelectric effect for supplying the electrical sensor. A data processing system is connected with the weather conditions detecting device via wireless link. A transceiver (40) provided for ensuring wireless link is fed by the electricity generation unit. The electricity generation unit is arranged in a thermoelectric module.
