    Hi All, Am new to the forum,live in Amsterdam. I do not know much about sensors, perhaps someone can guide/educate me.

    I need to replace a SYH-1 Humidity sensor in a humidifier but cannot buy 1 piece of the same, minimum order is 100 pieces. Does someone know of another compatible humidty sensor? I found one that looks similar HR202L. The only difference i could tell was that the SYH-1 is 23kΩ and the HR202L is 31.0kω . I dont have a clue if that matters or not. Below are the specs for both, perhaps someone here can enlighten me on the subject.
