I’m experimenting with building a remote humidity/temperature logger with a Spark Core. I’m using this sensor which I have used on previous Arduino projects without fault. http://www.freetronics.com.au/collections/modules/products/humidity-and-temperature-sensor-module#.VXEHHmTvPJw
Using it with the Core is not so reliable. It crashes and stops reading approximately once or twice per day and the only way to fix it is to pull power. The Core itself usually keeps working but obviously the readings are no longer accurate. I have added a 10k pullup resistor and while it seems to crash less often, it still crashes. As I said I’ve used these sensors & found them reliable previously but it doesn’t seem to play well with the Core. The two main differences I can see is that Arduino is 5v & Core is 3.3v and the DHT libraries are different.
Rather than trying to hack this to make it work I’d rather someone could point me to a sensor & library file that is known to work well with the Core. Can someone please point me to a working sensor?
Next up, I’m using an iphone charger to provide power for the core & sensor. Is there a better power supply I should be using & could this be contributing to the problem?
Thanks in advance for any help.
