OPB780Z, Reflective Color Sensor Assembly

Reflective Color Sensor Assembly OPB780Z .
The OPB780Z color sensor uses a light-to-frequency converter that combines 64 configurable silicon photodiodes (on a 144 um center and measuring 120.

Features

* High-resolution conversion of light intensity to frequency
* Selectable color output frequency
* Communicates directly with a microcontroller
* Sensor power supply operation (2.7 V to 5.5 V)
* LED power separate input
* Includes LED, Sensor and inte

Applications

* The output is a square wave (50% duty cycle) with a frequency directly proportional to reflected light intensity (irradiance). The light-to-frequency converter reads an 8 x 8 array of photodiodes that consists of four groups of 16 photodiodes each, segregated by color: 16 photodiodes with red filte
