The Yocto-Light-V4 device is a USB ambient light sensor (lux meter) which allows you to measure ambient light up to 83'000 lux. Measurements can be read directly 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-V2 which is not produced anymore. The Yocto-Light-V4 is recommended for low light measurements as it can detect down to 0.01 lux.
This circuit has been designed so that the sensor itself can be moved away from the USB part by a few meters: simply split the board into two parts and solder a 4-wire cable on the designated pads.
The Yocto-Light-V4 module is only available with a USB Micro-B connector. If you prefer USB Type-C connectivity, have a look at the Yocto-Light-V5-C.
This device can be connected directly to an Ethernet network using a YoctoHub-Ethernet, to a WiFi network using a YoctoHub-Wireless-n and to a GSM network using a YoctoHub-GSM.
USB cables and enclosures to be ordered separately.
