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.

MQ2 - Reading different gases - Sensors - Arduino Forum

· MQ2 - Reading different gases. Hi all. I am using this code example from Sandbox Electronics to read from the MQ2 gas sensor. However, all my readings are 0. If I use a simple analog reading on the specific pin, I get the expected analog values - from 0 to 1023, usual values around 250, and if I expose it to gas for example goes up to 1000.
