Hello, I have same problem with my Temp / humidity / solar kit. But for me C1 / C2 are 35v capacitor, not 10v. My board is rev 3. When i plug external power (~15v) temp grow up to 4°C than other sensors ( DS18B20 standalone). I don't understand why. I have checked circuit, everything seems OK...

Hello, Thank's for your reply, DS2438 and DS1820 reports same temp. When i connect humidity kit to barometer with term block, i have no problem. When i connect with RJ45, temp grow up to 4°... There is a LM 7812 for barometer and LM 7805 for humidity kit. normally Vin > Vout + 2V so you...

Hummmm, I think some componants are heating, when i remove power between barometer and humidity sensor, all is OK :P

hello, i have done more tests. When i remove barometer from bus, everything is ok. When i plug barometer, temp growing slowly... :P

Hello, I have build an hobby-boards humidity kit, everything is ok but when i run digitemp, i think temp is wrong, ~ 4° higher than real temp. I have checked this with digitemp and another DS1820 with passive power. When i have 16.8°C with kit, i have 12.44°C with standalone DS1820. What's...
