ThisLine Tracking Sensor is designed primarily to allow wheeled robots to follow lines. The sensor is comprised of an infrared transmitter/receiver pair emitting a certain IR frequency to detect reflectivity with high precision. The reflectivity threshold can be changed by adjusting the potentiometer, allowing you to set the sensitivity of the module.
Features of Tracking:
- Sensor adopts TCRT5000, high sensitivity
- Sensitivity adjustable digital potentiometer to adjust (blue)
- Modules can induction block from 0 to 3 cm
- Working voltage 3.3 V to 5V
- Output analog voltage (0 to 5 v)
- Digital switch output (0 and 1)
- Has a fixed bolt hole, convenient installation
- Small board PCB size: 3.2 cm * 1.4 cm
- Power indicator light (red) and digital switch output indicator light (green)
- Comparator USES the LM393 chips, work stability
- Detection reflection distance: 1mm to 25mm
- Comparator output, signal waveform, driving ability is strong, for more than 15mA
