I have I2C sensor and two Arduino. I want to read the sensor data from two Arduino at the same time. Can I connect the sensor to SDA-SCL pins of two microcontroller as shown in the picture?
The sensor works with one arduino but I have not tried with two arduino. Anyone tried? If it is not possible lin this way, what should I do in programming?
The sensor is a slave. It responds to one master at a time. You can't have two masters at the same time.

Query the sensor at different times?
Or you could have one Arduino be the master and the other a slave.
Then the master Arduino takes all readings and sends them to the slave Arduino.
