Description
In the smart car DIY process, we often use a line tracking sensor to make the smart car follow a line.
The keyestudio 3-channel line tracking module actually is an infrared sensor. The component used is a TCRT5000 infrared tube.
The working principle is to use the different reflectivity of infrared light to color, converting the strength of the reflected signal into a current signal.
During the detection, black is active at HIGH level, and white is active at LOW. The detection height is 0-3 cm.
We have integrated three groups of TCRT5000 infrared tubes on a single board, convenient for wiring and control.
Turn the adjustable trimpot to adjust the module’s sensitivity.
The module comes with two 3mm positioning holes for mounting on other devices.
Note: before testing, turn the potentiometer to adjust the sensitivity. The sensitivity is the best when make the LED at the threshold point between ON and OFF.
Technical Parameters
- Operating voltage: DC 3.3-5V
- Detection height: 0—3cm
- Interface: 5pin of 2.54mm pitch
- Positioning hole diameter: 3mm
- Dimensions: 42mm*31mm*7mm
- Weight: 6.6g
- Environment attribute: ROHS
Wiring Diagram
Test Code
int sensor1 = 2; int sensor2 = 3; int sensor3 = 4; int val1; int val2; int val3; void setup() { Serial.begin(9600); pinMode(sensor1, INPUT); // set sensor to input mode pinMode(sensor2, INPUT); // set sensor to input mode pinMode(sensor2, INPUT); // set sensor to input mode } void loop() { val1=digitalRead(sensor1); Serial.print("val1:"); Serial.print(val1); val2=digitalRead(sensor2); Serial.print(" val2:"); Serial.print(val2); val3=digitalRead(sensor3); Serial.print(" val3:"); Serial.println(val3); delay(200); }
Test Result
Done uploading the code to control board, open the serial monitor and set the baud rate to 9600.
When the tacking module detects black line, output 1; detecting white line, output 0. As figure shown below.
