si7021 sensor I2C interface slave address

yef smith · Sep 11, 2020

Hello ,from the manual as shown bellow the address of the slave 0x40 but from table 10 shown bellow its 10000000 which is not 0x40.
So what is the slave address for the I2C?
Thanks.

NB: only the lower seven bits are shown.

0X40 in binary is b'0100 0000'. That's the 7th bit.
