Use suggestions：

Suitable indoor temperature and humidity environment in summer

The most suitable indoor temperature in summer is 23°C to 28°C, and the humidity is 30%RH to 60%RH. Most people in this range feel comfortable. In an air-conditioned room, people feel most comfortable when the room temperature is 19°C to 24°C and the humidity is 40%RH to 50%RH. If you consider the influence of temperature and humidity on people's thinking activities, the best indoor temperature should be 18℃, and the humidity should be 40%RH to 60%RH. At this time, people are in a good state of mind and their thinking is the most agile.

Suitable indoor temperature and humidity environment in winter

In winter, the temperature is 18°C to 25°C, and the humidity is 30%RH to 80%RH; in winter, when the indoor humidity is too high, heat conduction will be accelerated, making people feel cold and depressed. When the indoor humidity is too low, a large amount of moisture in the upper respiratory tract mucosa will be lost, and people will feel dry and dry, and they will be susceptible to colds.

If the humidity is insufficient, it is best to use a humidifier in time

Tips:

Like the measurement range, measurement accuracy is the most important indicator of the sensor. Each increase of one percentage point. For the sensor, it is a step up, or even the last level. Because to achieve different accuracy, the manufacturing cost varies greatly, and the selling price also varies greatly. For example, an imported cheap humidity sensor is only a few dollars, while a full-humidity humidity sensor for calibration costs a few hundred dollars, a difference of nearly a hundred times. Therefore, users must tailor their clothes, and it is not advisable to blindly pursue "high, precise and sharp".
