DESCRIPTION
These QTR reflectance sensor arrays feature seven IR emitter/phototransistor pair modules in a high-density (4mm pitch) arrangement, which makes them well suited for applications that require precise detection of changes in contrast, such as line sensing.
Unlike the original QTR sensor modules, these units have integrated LED drivers that provide brightness control independent of the supply voltage, which can be anywhere from 2.9 V to 5.5 V, while enabling optional dimming to any of 32 possible brightness settings.
There are separate controls for the odd-numbered and even-numbered LEDs, which gives you extra options for detecting light reflected at various angles.
This “QTRX” versions feature higher-performance sensor modules with lenses, which allow similar performance to other similar sensors but at a much lower IR LED current.
Please Note:
- Headers or connectors are not included.
