How to connect BMP180 and SHT21 sensors together
hi,
i'm pretty new forgive me if ask dumb question..
i'm trying build kind of weather station. need temperature, barometric pressure , relative humidity.
in order bought bmp180 sensor - pressure, , sht21 sensor temperature , humidity. plan connect them arduino mega.
both sensors use i2c how can connect them , read results both of them? acquisition doesn't have simoultanious purposes.
thanks!!

i2c bus multiple devices can connected sda , scl pins, daisy chain them ...
