[suitable indoor temperature and humidity environment in summer
The most suitable indoor temperature in summer is 23ºC to 28ºC, humidity is 30%RH to 60%RH.Most people in this range are comfortable.In the air-conditioned room, people feel most comfortable when the room temperature is 19ºC to 24ºC and the humidity is 40%RH to 50%RH.If the influence of temperature and humidity on people's thinking activities is considered, the optimal indoor temperature should be 18ºC, and the humidity should be 40%RH to 60%RH. At this time, people are in good mental state and have the most agile thinking.
suitable indoor temperature and humidity environment in winter
Winter temperature is 18ºC to 25ºC, humidity is 30%RH to 80%RH;Winter, indoor humidity is too big when, can accelerate heat conduction, make a person feels gloomy and cold, depressed.When indoor humidity is too low, the moisture of mucous membrane of upper respiratory tract is lost in great quantities, the person can feel dry mouth dryness, catch a cold easily.
If the humidity is insufficient, it is best to use the humidifier in time
Little knowledge about temperature and humidity sensor
As with the measuring range, the measuring accuracy is the most important index of the sensor.Every percentage point.For sensors, it's a step up, even a step up.Because to achieve different accuracy, its manufacturing cost varies greatly, the price also varies greatly.For example, a cheap imported humidity sensor costs only a few dollars, while a full humidity sensor for calibration costs hundreds of dollars, or nearly a hundredfold.Therefore, users must tailor their clothes to suit their needs, and should not blindly pursue "high, fine and sharp".
