protect pcb

I need to place Wireless Sensor Network PCBs in outside environment. It won't be directly esposed to wind or rain but it needs to relaiably work for montsh in harsh conditions of temperature and humidity.

I don't know if there's some insulating spray or paint that is commonly used to do the work. Please, can anyone give me an advice?
