| May 24, 2017 at 5:57 | comment | added | user541686 | @MartinArgerami: Sorry, but I'm pretty darn sure you're wrong. Fog normally occurs at a relative humidity near 100%. However, fog can form at lower humidities, and can sometimes fail to form with relative humidity at 100%. Condensation on salt particles has been observed to occur at humidities as low as 70%, thus fog can occur even in relatively dry air in suitable locations such as the California coast. | |

| May 23, 2017 at 13:45 | comment | added | Martin Argerami | @JulianKnight: as I mentioned, 80% humidity is very common where I grew,up, and houses are not covered in mold. At the other end of the spectrum, it is typical in Canadian houses during the winter to be below 20% (unless you have a very good humidifier), and we still survive fairly well :) | |
| May 23, 2017 at 13:41 | comment | added | Martin Argerami | @Mehrdad: fog occurs when the air is saturated, which is the definition of 100% humidity. | |
| May 23, 2017 at 11:25 | comment | added | Julian Knight | All electronics will indeed specify something like that in order to cover themselves just in case. In practice, things tend to be different. Some sensors wont work correctly outside parameters but general electronics systems are remarkably resilient actually. Power spikes are the big killer. Corrosion the main issue for high humidity. | |
| May 23, 2017 at 9:14 | comment | added | Jonas Schäfer | Most data sheets I’ve read have something like "up to n% humidity (non-condensing)", which suggests the opposite of what you claim. | |
| May 23, 2017 at 6:04 | comment | added | Julian Knight | I think that fog can only really happen at 100% since by definition it is the amount of moisture in the air exceeding its capacity to hold it - but I'm not a weather expert. | |
| May 23, 2017 at 5:59 | comment | added | Julian Knight | >60% humidity in indoor spaces is certainly considered unhealthy as it encourages mold spoors which can have serious health effects. External humidity is different due to air movement. <40% humidity indoors is also considered unhealthy as it dries tissues, especially in the throat (I believe). | |
| May 23, 2017 at 5:58 | comment | added | user541686 | @MartinArgerami: I think fog can occur at less than 100% humidity? | |
| May 23, 2017 at 4:33 | comment | added | user366447 | Oddly enough, if the humidity goes down far enough, you have ESD hazards. Lower humidity increases the maximum spike voltage you can unintentionally deliver to electronics. | |
| May 23, 2017 at 0:26 | comment | added | Martin Argerami | I'm surprised by this answer. I grew up in a place where more than 80% humidity is very common, yet everyone's cellphones work fine. Anywhere, whenever there is fog, you are at 100% humidity, and phones still survive that. | |
| May 22, 2017 at 20:59 | comment | added | TemporalWolf | Side note: High humidity is not "very unhealthy" for people, there are places, like Okinawa, Japan, which experience >80% humidity for several months every year. | |
