MQ-2 sensor does not detect smoke - Arduino Forum

· I have an MQ-2 sensor connected to Arduino Nano and i read values with analog A0 pin. Arduino 5V goes to the VCC pin and the Arduino Ground to the GND pin on the sensor. When i hold an butan torch under it i can se the values in serial monitor changes from around 100 to 5-600. But it does not seams to detect smoke from for example my solder iron. (solder fume). It does not detect smoke …
