Hello, I have a Grove - Multichannel Gas Sensor and I am getting the following values:
And I am comparing them with the sample image from the wiki and they don’t even have the same order of magnitud. How can I make sure that the readings from the sensors are correct? Thank you.
to calibrate the sensor, you need to use another calibrated sensor to offset the values.
Wouldn’t it be more safer to have specific sensors for each gas you want to detect? Maybe it’s a bit more expensive but an ammonia gas detector has to be super specific to be able to detect it
