GAS SENSOR MQ-6



  • Hello!
    I'm using MQ-6 with my Obniz.
    The output value of this sensor using obniz js library is in voltage.
    Do you know how the formula to convert it to ppm value?
    Thank you.



  • @Yunita-Siagian Hello,
    As I mailed to you, It's value is voltage.
    To convert to ppm value, You need to calibrate the sensor before use it.
    But we don't have knowledge to calibrate it and how to convert it to ppm value. Please refer other articles on the internet.
