MQ-2 Gas/CO/Rauch Sensor an D1 Mini - Deutsch - Arduino Forum

· Hallo zusammen, ich versuche einen MQ-2 an einem D1 Mini ans laufen zu bekommen. Ich hab das in der Library enthaltene Sample kompiliert und hochgeladen. Ich benutze den A0 Anschluß um Daten zu empfangen. Leider bekomme ich komische Werte: LPG: CO: SMOKE: Wenn ich den analogen Anschluss trenne bekomme ich 0 Werte, also kommen die Werte vom MQ-2.
