Re: MQ135 air quality

Did you power the sensor with 5V?
With 3.3V its not going to work.
You need as well a voltage divider to get output down to 3.3V

Re: EEPROM lifespan?

The water meter only writes if there are updated values.
Personally I don't think water flows for more then an hour a day. So take the 5 months times 24.

Re: HC-SR04 and DS18B20 help?

Your just updating the temperature sensors in code:
zunoSendReport(i + 1)
and zunoSendReport(1);

You need to add:
zunoSendReport(3);

Re: Z-UNO based weather Station (German description)

Thanks for your testing. HC2 indeed seems to have issues with values >32k. Initially I used long, 32k was limitation as well, but from time to time a neighbouring channel showed spikes of 32k. Could be when value got over 64k. For the time being I will devide the result by 4 and apply correction on ...

Re: Z-UNO based weather Station (German description)

Polto, sure it is fine if post it on your web site. Actually that is not my blog, just wrote a guest report. The Z-UNO code is poorly commented at the moment, I can add some comments to explain a bit better the logic used. If you need any support let me know. One challeng I have is the BH1750 only g...
