    Even if I put the sensor next to a car exhaust I still get 0.2 ppm constant. Could be the sensor broken? Thank you

    If I have pin D10 connected, should I also connect the 5V to the sensor or the D10 pin in enough? If I connect the 5V wire to the sensor (to the arduino) I always get 0.00 PPM, if I remove the 5V wire I get 0.21 PPM. Can you please repeat which wires should I connect to the arduino? Thank you very much
