Resistance value of MQ-135 is difference to various kinds and various concentration gases. So,When usingthis components, sensitivity adjustment is very necessary. we recommend that you calibrate the detector for100ppm NH3 or 50ppm Alcohol concentration in air and use value of Load resistancethat(RL) about 20 KΩ(10KΩto47 KΩ).
The MQ-135 measures a gas concentration of 10 to 1000ppm and is ideal for detecting a gas leak, as a gas alarm or for other robotics and microcontroller projects. The SENSORS of the MQ series use a small heating element with an electronic-chemical sensor. They are sensitive to a wide range of gases and are suitable for use in rooms.
