Hi im looking for a temperature and humidity sensor in one or a separate sensor combination that can interface with a atmega via i2c,spi,analog and with some arduino library support if possible.It is to be used both outdoors and indoors and needs to be capable of the following:
Negative temperatures
Reasonable accurate (no more than 1°C-2°C out if possible)
Temperature resolution in centigrade of .1°C or .01°C (so i can get readings such as 24.98°C etc)
Humidity resolution of .1% would be nice(60.4% humidity etc)
Which sensors do you recommend ?
Thx
