The Xiaomi Smart Evaporative Humidifier has a humidity detection function. The sensor is on the back of the humidifier. Please make sure that there is no obstruction or heat source interference on the back of the humidifier.
If different devices display different humidity, you can refer to the following points:
1. The humidity measured by the hygrometer will be quite different due to different indoor environment detection positions. Therefore, the hygrometer can be placed near the humidity sensor of the humidifier, measuring for 10 minutes and then you can check the value after it stabilizes;
2. Different products have slightly different humidity detection principles and working methods. The humidity detection value is related to factors such as airflow and ambient temperature. The values detected at different locations and different devices will have certain differences. The Xiaomi Smart Evaporative humidifier has been experimentally inspected and the error compared with the standard instrument in the laboratory environment is ±5%.
