I now built in an ESP measuring the temp inside to warn me if the temperature goes above -15 deg C. Still I wait für a small ups (apc) beeing delivered for ...

Re: Sensair S8

Hi guys,
Good news - works perfectly. I´m a bit embarrassed, as it was my fault (wiring) - sorry for bothering. :oops:
Do I have to do some calibrating? anything?
Are the aliexpress S8´s bad copies or lower of quality?
thanks for your support over the last couple of days!!!

Re: Sensair S8

But still no value of the device. logging of serial is disabled.
TX wired to D7
RX wired to D8

hmmm.. still theres the hint of connecting D8 via a transistor?? Ignore it?
thanks for your help!!!

Re: Sensair S8

In addition i swaped the pins: now TX is wired to D7 with the result, that the nodemcu wont boot anymore.
Do I need a PNP Transi? Is there a schematic available? Thank you so much!

Re: Sensair S8

Should I swap the used GPIO Pins?
And why would I need to insert a PNP-Transistor to buffer D8?

Re: Sensair S8

Dear all, A friend and myself try to grow mushrooms (!to eat not to fly) here in vienna on old coffee grounds. While breeding the mycel produces Co2 heat and need a certain amount of moisture. So we planned to measure CO2 with first MH-Z19 and Senseair S8 (both via China). Actually i failed with bot...

Raspi? best yours rob Hi, Here's a link to a PDF for a simple exercise I did with my IoT students. http://resources-area.co.uk/node-red-flows/moisture_meter.pdf We used the very inexpensive resistive sensor and then used a transistor...
