MQ135 Sensor - calibrate and configure - DIY Projects

06/05/2020· Before you start using this MQ135 Sensor, they need to burn-in. This means you have to connect them to 5V and let them run for at least 12-24h. Afterwards, we have to calibrate the measurement . I you received a sensor like mine, you will notice that this little resistor whoch is connected against ground is arround 1K Ohm, this as a bit of a problem as the basic arduino libary …

Measure CO2 with MQ-135 and Arduino Uno - Rob's blog

04/01/2017· This is no good of course, so something must go wrong in the calculations in the MQ135 library. Or I am using a MQ-135 sensor with a bad response curve. The next day I have tested the same with another MQ-135, but the results were about the same. Wrong formula in the library. The formula to calculate the resistance of the sensor is wrong.

MQ-135 Gas Sensor Pinout, Features, Alternatives ...

27/02/2018· How to use MQ-135 sensor to measure PPM. MQ-135 gas sensor applies SnO2 which has a higher resistance in the clear air as a gas-sensing material. When there is an increase in polluting gases, the resistance of the gas sensor decreases along with that. To measure PPM using MQ-135 sensor we need to look into the (Rs/Ro) v/s PPM graph taken from the MQ135 datasheet. The above …
