How do sensors identify different gases using Arduino code?
Hello dikshakumarikangra07
Read and study the data sheet of sensor hardware selected.
try a web search for mq135 sensor arduino, e.g. interfacing-mq-135-gas-sensor-arduino
also look at the MQ135 library
A very strange sounding question... although maybe it's because English is not my native language.
Do you think that using an arduino, the sensor detects gases in a different way than using any other microcontroller?
The sensor is sensitive to all the gases mentioned , but cannot identify the make up of the gas ( ie can’t identify CO in a mixture of gases to which it is also sensitive ).
So what you want to do is impossible
( it maybe that it is differently sensitive at different heater voltages to specific gases , but that’s a research area)
Most Arduino gas sensors don't identify any specific gas, but there are a few, like this CO2 sensor, that use laser absorption to detect and measure a specific gas.
Is a laser sensor able to detect colors using LED light?
Colors of what? A gases?
color of an object or light.
