YFROBOT QTR-5RC Tracking Line Sensor Infrared Tracking Sensor Robot-M
Description:
- QTR-5RC has 5-channel infrared detector, different from the traditional sensor, not just simply give high/ low level or analog value according to reflecting strength
- Before using, it should be configured with corresponding pins as high level, then set pins as input mode, the start timer, caculate high level time until the level changes to low level
Parameters:
- Working voltage: 3.3V-5V
- Working current: <70mA
- Sensing distance: 7mm(max) 4mm (best)
- Dimension: 6.9*1.2cm
- Package weight: 3.9g
Operation Method:
- Fix the sensor under the robot at the front part, 3-5mm away from ground is better
- Do not use sensor at the strong light environment, which can produce interference signal
- Tracking detector reflects different intensity to different color, white is the most sensitive, black is the weakest
- Sensor has 5 channel input, before using it should be configured with corresponding pins as high level, then set pins as input mode, the start timer, caculate high level time until the level changes to low level.
- En can not be used at the normal situation, it can control infrared detector switch by digital pins, to reduce more consumpsion
