Description
The sensor enables colour detection in 8 bit RGB format and light intensity measurement in lx. It is powered from 3.1 V to 5.5 V, which makes it compatible with systems working with 3.3 V logic (e.g.Raspberry Pi) and 5 V (e.g.Arduino). The system can work in three measurement modes: RGB, intensity and RGB and intensity. The data are sent through the UART serial interface (RX and TX pins) as numbers separated by commas.
The red wire is the supply voltage, black ground, green TX, grey RX - details on the diagram.
Thanks to a durable housing and a layer of epoxy resin, the sensor is resistant to external conditions. This means that it can be used outdoors to study, for example, changing nature by measuring plant colours.
