Sir what type of gas sensor u use in fritzing, why i cnt find mq135 in fritzing ?

[rishitgarg]

Is dht 11 sensor required or we can only measure gas value with mq 135 sensor

[flavoursofpavagada]

Sir I cannot able to choose the port what to do for this ?

[onlycoding]

hi sir it giving nan input for temperature and humidity and 0 for mq135 pls respond

[maristelakrystalp.]

how can i change may port com3 into port com5?

[srinidhisri]

it is giving nan values for temperature and humidity

[JigsawXop]

Can we use bylnk instead of thinkspeak

[nikhiledits]

Sir, Where can we get this source code
