Yocto-light-v3

Yocto-Light-V3

  

The Yocto-Light-V3 device is an USB ambiant light sensor (lux meter) which will allow you to you measure ambient light up to 100'000 lux. Measurements can be directly read via USB or stored on the device internal flash for later retrieval when connected again by USB.

This device is a replacement for the Yocto-Light V1 which is not produced anymore. THe response to light is closer to human eye than the Yocto-Light-V2.

This circuit has been designed so that the sensor itself can be moved further away from the USB by a few meters: simply split the board into two parts and solder a 4-wire cable on the designated pads.

This device can be connected directly to an Ethernet network using a YoctoHub-Ethernet, to a WiFi network using a YoctoHub-Wireless-g, it can even be connected to a GSM network thanks to the YoctoHub-GSM.

Hi,

I'm suprised new desktop motherboards don't come with light sensors and was therefore very happy to find this product.

You claim that it don't need any drivers. Does that mean that Windows will automatically register this as a light sensors common in laptops and use it to adjust my external screens brightness?

Or is that a no go since my screen is external? (However, this tool seems to indicate that it is possible for software to adjust my monitor: http://clickmonitorddc.bplaced.net/)

Thankful for any help I can get.

Yoctopuce, get your stuff connected.
