New sensors in local instance!
09 Sep 2015Hardware
Some time ago I bought a few sensors. Two of them were:
A few days ago I had time to use them in local HomeIO instance.
Digital sensor is much more accurate than analog. Digital sensor has 0.1°C resolution, while analog one has 0.5°C effective resolution when using ADC converter. You can change reference voltage to increase resolution, but it’s not recommended in present situation, when there are other analog sensors.
Outcome
I bought another digital one and installed it outside few moments ago. I hope this will result in interesting conclusions over time.
Measurements:
- internal temperature - 21.4 °C
- internal humidity - 45.2 %
- external temperature - 13.3 °C
- external humidity - 69.5 %
