How To Use MQ-135 Gas Sensor - Codrey Electronics

2020-07-05· Since sense resistance (Rs) value of MQ-135 gas sensor is different for various kinds and various concentration of gases, sensitivity adjustment becomes very necessary. The datasheet recommends to calibrate the MQ-135 sensor for 100ppm NH3 or 50ppm Alcohol concentration in air and use value of the load resistor (RL) about 20KΩ (10KΩ to 47KΩ).
