    Hi Che Yi,

    TMP102 device has four addresses that you can configure to 0x48, 0x49, 0x4A, 0x4B via the pin address of ADD0 by connecting to GND, V+, SDA, and SCL respectively. You cannot configure the device's addresses via the software. The default address is 0x48, ADD0 = GND. If you want to change the address, you need to remove R3 resistor then connect to V+, SDA, and SCL to change the address.

    Hope this helps. Let me know if you have further question.
