Abstract：Currently,there is a lack of active dehumidification solutions for car light anti-fog measures.The existing car light dehumidification solutions are traditional and ineffective.So,a better solution is needed.Through designing the circuit board,the switch judgment of the dehumidifier function can be realized.The designed circuit board can read the temperature and humidity signal from the sensor circuit board and judge it from the setting temperature and humidity,and decide whether to output the working voltage to the dehumidifier based on the judgment result,after that it let the dehumidifier work when the temperature is higher than 40℃and the humidity is higher than 83%RH,and not work in other situations.
