How to check if my Philips humidifier's air humidity sensor is working

Remove the cover of the air quality/humidity sensors and then gently blow moist air into the opening. After a while, the CURRENT HUMIDITY indication changes. Note that if the initial CURRENT HUMIDITY indication is already 60%, the indication cannot show an even higher humidity when you blow moist air towards the sensor.
