Hi, thank you fo sharing, I plan to make it and I ordered MHz19 sensor, meanwhile there is a little error in the schema, MHZ and OLED GND line are not connected to ground.

How do you power it? via USB?

Thanks

XylenC4 commented 5 years ago

Hey, yes USB power is good enough. I will check the "shematics" tomorrow. Thank you!

XylenC4 commented 5 years ago

i fixed it and some other things! Thanks you for your remarks.

they still don't seem connected to ground but to 5v input?
