Hi @trickster123,
your sensor uses the I2C protocol, and its address cannot be changed and therefore cannot use more than one on the atmega I2C bus..
But with TCA9548A device you can use up to 8 sensors with the same address.
You can connect up to 8 TCA9548A on the same mega I2C bus and thus have up to 64 sensors with the same address.
