The TCRT5000 reflectance sensors array is intended as a line sensor, but it can be used as a general-purpose proximity or reflectance sensor. The module is a convenient carrier for eight IR emitter and receiver (photoresistor/photodiodes) pairs evenly spaced at intervals.
Each phototransistor equips a pull-up resistor to form a voltage divider that produces an analog voltage output between 0 V and VIN (which is typically 5 V) as a function of the reflected IR. The lower output voltage is an indication of greater reflection.
Features
Potentiometer to adjust the sensitivity of the individual sensors.
The module is a convenient carrier for eight IR emitter and receiver pairs evenly paced.
Uses 8 sensors for best resolution
Great useful in building fast line following and grid navigating robots
Comes with easy to use digital outputs with a direct connection to microcontrollers
The array has mounting holes of 3mm diameter for easy mounting
