Description

This Digital Line Following Sensor - 8 Array has 8 IR LED/phototransistor pairs, making it a great detector for a line-following robot. Each sensor has its own digital output also a potentiometer to adjust the sensitivity of the all sensors. RoboticsBD

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.

The outputs are all independent, but the LEDs are arranged in pairs to halve current consumption. The LEDs are controlled by a MOSFET with a gate normally pulled high, allowing the LEDs to be turned off by setting the MOSFET gate to a low voltage. Turning the LEDs off might be advantageous for limiting power consumption when the sensors are not in use or for varying the effective brightness of the LEDs through PWM control. RoboticsBD

The LED current-limiting resistors for 5 V operation are arranged in two stages; this allows a simple bypass of one stage to enable operation at 3.3 V. The LED current is approximately 20-25 mA, making the total board consumption just under 100 mA. RoboticsBD

Features:

  1. The module is a convenient carrier for eight IR emitter and receiver pairs evenly paced.
  2. Distance between each IR Sensor: 15mm
  3. Uses 8 sensors for best resolution
  4. Great useful in building fast line following and grid navigating robots
  5. Comes with easy to use digital outputs with a direct connection to microcontrollers
  6. The array has mounting holes of 3mm diameter for easy mounting. RoboticsBD
