Can not read data from BMP280 Digital Pressure sensor + Raspberry Pi

[saiful-sdsl]

Hi,
I am using a BMP280 digital pressure sensor for my research project. I have assembled this sensor with a Raspberry Pi. My target is to read sensor data using the provided python code (downloaded from here: https://github.com/ControlEverythingCommunity/BMP280).

While running the python code it thowring the output as like below:

Traceback (most recent call last):
File “BMP280.py”, line 16, in
b1 = bus.read_i2c_block_data(0x76, 0x88, 24)
IOError: [Errno 110] Connection timed out

Then I tried to run the following command to see the available hardware attached to the Pi:

sudo i2cdetect -y 1

It only showing
pi@raspberrypi:~ $ sudo i2cdetect -y 1
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: – -- – -- – -- – -- – -- – -- –

50: – -- – -- – -- – -- – -- – -- – -- – --
60: – -- – -- – -- – -- – -- – -- – -- – --
70: – -- – -- – -- – --

Is that means Pi is not detecting any Sensor?

Now, my questions:

If Pi is not detecting the sensor, what needs to do to resolve this problem?
Then, how to get sensor data using python code?
