I suspect that sensor is ok. The problem is the datasheets I and others are highlighting are correct in that the sensor is 3.3V BUT BUT BUT if you look at the 'board' you will see a black chip with 3 silver legs, 2 on 1 edge 1 on the other. I will make a medium wager that is a VOLTAGE REGULATOR that take in 5VDC and puts out 3VDC or 3.3VDC
There are 3 chips like that on the board, one above the LED pin, one above the SDA pin and one up top by the word Sensor.
If you can look at the 2 chips near the SDA pin and get the part number it would confirm my hunch.
Now my hunch as I am not trained and am an 83yo autistic person but how does the VR work with a 3.3VDC board? Normally the input Voltage needs to be a volt ot two above the output. I think I saw in the datasheets that the output only needs to be 1.8VDC so that would explain the 5 or 3 statement.
