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.
