waterprof temperature and humidity sensor like ds18b20

I am using ds18b20 temperature sensor gives quite accurate temperature so i have it hanging outside my home even in rain , however i can't find anything like ds18b20 waterproof sensor for measuring humidity .

can anyone suggest a waterproof low cost sensor for measuring humidity ?


Because you are measuring a moisture level in the air, the active part of the sensor has to be in contact with the air.

You can make an enclosure for the humidity sensor that allows air flow, but not direct water droplet contact.
