Why is there condensation on the lens of the Xiaomi Smart Projector L1 Pro?

The reason for the condensation phenomenon is that the temperature difference between the optical lens and the ambient temperature is too large, causing condensation after the lens in the projector comes into contact with the air, thus blurring the image. This problem is normal.
To avoid condensation on the lens of the Xiaomi Smart Projector L1 Pro, please refer to the following details:
1. Avoid large temperature differences. When the projector is moved from a low-temperature or high-temperature environment to a high-temperature or low-temperature environment, the temperature difference between the two environments should not exceed 10°C. You can leave the projector for 1 to 2 hours to allow it to return to the ambient temperature, and then use it again. This problem will not occur;
2. If the projector has been used and there is water mist (condensation) inside and outside the lens, the image will appear blurry and shiny. After the projector is turned on for 20 to 30 minutes, the image will return to normal and the projector can be used normally.
