Presenting MQ sensors low-cost gas and pollution

Feb 19, 2019So I will not repeat this. To calculate this ratio, we loop over all gases and sensors and store this in ppm_values[mq_sensor][gas]. for gas, curve in cfg.CURVES[mq_sensor].items(): ppm_values[mq_sensor][gas] = get_ppm(mq_values[mq_sensor], curve) Temperature, humidity and pressure. Besides the gas sensors, we read the temperature, humidity and ...
