i2c with 2 sensors and same physical address

How can i do that? is it possible to use 2 same physical address sensors with the i2c bus or not?

If you think about it (or read the I2C spec.), the answer would be obvious - no.

But many I2c devices (slaves) have one or more address pins, to operate several (i.e. 2^n for "n" address pins) devices on one bus. Check the datasheet of your undisclosed slave.

If not, you can use separate I2C buses, or try other "hardware tricks".

Hi Amit Ashara i tried it on Tm4c and its working thanks for that..But now i switched to Rm46 herculus safety microcontroller.Is there any way of doing the same thing with the Rm46 mcu?

I suggest to ask this question in the "Hercules Safety Microcontroller" forum. Guess you will find more competent answers there ...

I am bound to do that only on Safety mcu. I need to build a safe system.for that if i am using  a safe mcu so i need not to bother about the safety of mcu but rest of the system.

I'm pretty sure that's an oxymoronic sentence.

Thanks Amit and Robert for your reply.
I am a master student and working as an student assistant in a research institute.So i am a learner and new to all these things. Actually the idea was to develop a safe system with SIL3 and for the micro controller part i though of using two processor(or microcontrollers) and comparing both the results.Then i found about the safety mcu. it already have two processors and internal comparing solution.So instead of using two mcu and then comparing the results i though of using only the one safe mcu.
