Colswe Light Logger, is an USB ambient light sensor (lux meter). It measures ambient light up to 1000.000 lux. Measurements can be directly read via an USB connection or they can be stored in its internal flash memory for later retrieval via the USB connection.
Colswe Light Logger response to light is close to human eye.
The sensor part can be detached from the main USB board and moved a few meters away using a 4-wire cable, soldered on the designed contact pads.
Colswe Light Logger can be connected directly to an Ethernet network with a Colswe Hub Ethernet, to a WiFi network with Colswe Wireless SR or to a GSM network with a Colswe Hub GSM.
