Why is this person’s house 82 degrees?

At 42% humidity, I’m guessing they live in a subtropical climate. Florida’s?

  Maine is relatively dry. My house generally stays around 40-60% humidity year round except during the coldest parts of the winter, independent of the outdoors in both extremes.

    Relative humidity is a function of air temperature. 50% humidity at 60F is relatively comfortable, but 50% humidity at 90F is much more uncomfortable. What is really happening is the dew point is closer to your ambient surface skin temp, so water has a harder time evaporating/starts to collect. Since air holds more water at higher temps (and a lot more, 90F air can hold almost 3x as much as 60F air), just comparing humidities without considering temp doesn't say much.

  No, St Louis: https://www.weather.gov/lsx/monthTab https://www.weather.gov/lsx/monthTab It was in the upper 80s/lower 90s throughout July and August, when this data was likely collected. And relative humidity hit 80-90% every morning, averaging about 65% as it warmed up. It's sticky in summer. I live in Michigan, and even with a cool breeze from our magnificent freshwater lake, half an hour inland it's similarly hot and humid. I kept our house at 78 when we're home, 82 when it's just the dog, and 76 when company comes over. I think the air conditioner keeps humidity in the 40% range, though I'm reading this article because I lack a hygrometer/air quality sensor and don't really have hard numbers for that, only that humidity is significantly less indoors than out. Also, he mentions that the orientation of the case causes convection off the ESP8266 to increase the air temperature by a couple degrees (Farenheit). If you're one of the Silicon Valley HN readers looking to move to the wide open spaces and relaxed culture of the Midwest, do be aware that climate is a big deal; coastal California's perpetual mild climate is an aberration.

    As a Midwest native, but SF resident, I don't think I could ever move back due to the weather.

    In Tennessee myself and it is only just now getting to a temperature/humidity that is bearable to be outdoors. March spring hits and the pollen is crazy until June and by then it's too hot to really be outside without tree cover from 9am-8pm until around now. My area is one of the worst pollen places in the country. You owe it to yourself before moving to look at a pollen map as well.

> The case is well-ventilated, and my only complaint is the natural convection causes very-slightly-warmed air from the WeMos D1 and CO2 sensor to pass over the temperature and humidity sensor on the top, meaning those readings are always a bit higher than ambient—at least in my office. Likely because of this.

  Heh, this. I keep the thermostat between 78-80°F during the summer months (which allows the A/C to run enough to keep humidity down below 50%), and between 68-72°F in the winter.

Here in South Texas I keep my house at 78° during the daytime in A/C season (that's typically March-November, plus some days the other months). If the ceiling fan's aren't on, and the air isn't moving around properly, it can easily get up to 82°. It's perfectly comfortable. (You acclimate to it) Understand, the average high is in the mid to upper 90's and trying to get a home a/c to cover a 20+ temperature difference is difficult and significantly drives up the monthly power bill.

Why is this person’s house 82 degrees? When I lived in the desert, 82° was comfortable for me. Generally, the humidity was below 10% (NWS reading, as most cheap consumer sensors are not precise below 10%). But even in monsoon season, when the humidity would spike, it was still fine. I guess you get used to it. My wife never did, so when she came home from work she'd turn the temperature down to 78°.

82°F == 27.7°C https://en.m.wikipedia.org/wiki/Fahrenheit https://en.m.wikipedia.org/wiki/Fahrenheit
