I am trying to link a digital thermo sensor (MR003-001) to the I2C pins on A+ Pi. I have enabled I2C connection in raspi-config, and download I2CdevTools. user is in i2c group, I provided a 3.3V input to the sensor, which can accept between 2.7 and 5.5V. The physical address is 0x48 by default. When I am running i2cdetect -y 1, nothing is detected. I am afraid I may have damaged the sensor (which is brand new). I have only seen a few topics about I2C integrity checks, and all of them were with devices which had worked at least once before. I don't really know what to do to make this sensor visible on I2C port, or at least ensure it isn't broken.
Thanks in advance for any kind of help.
