What kind of ambient light sensor is this GY-39V3 really using?

[ckuethe]

Like the subject says, what kind of sensor is this, really?

So this GY-39 board was full of surprises; the listing said BME280+MAX44009 and I got .. not that.. There is limited documenation about the board.

Using an i2c scanner sketch, I determined that this board has 3 i2c devices at 0x53, 0x70, and 0x76. The SHTC3 works with adafruit-shtc3 and the SPL06 has SPL06-007. I prefer the BME280, but as long as I get reasonably accurate temperature, humidity, and pressure readings it's ok.

Unfortunately none of the MAX44009 libraries and demo sketches I could find (luxmeter, max44009_test) want to have anything to do with the ambient light sensor. Not surprising, since the MAX44009 is supposed to be at 0x4a or 0x4b.

I spent a while looking for datasheets of i2c ambient light sensors whose i2c address is 0x53, as well as just looking at photos of i2c ambient light sensors... there's some resemblance to some Vishay and Broadcom products, but I haven't found a good match. Just for fun, I tried a few of the libraries for these products and didn't get any sensible results (eg. covered with my hand or pointing a flashlight right at the sensor would return a constant).

So I ask you, my fellow nerds and hackers... do any of you know what this light sensor really is?

3rd chip is LTR-308ALS @ Ox53

Thanks for the info on the other 2 chips, i got the same one, all 3 chips work per data sheet.
Edited, Correction from Manufacture, working with vendor. Chips are, SPL06-007, SHTC3, LRT308ALS, Previously mentioned library works as well with UV return as 0.
