Keyestudio 3 Channel Infrared Tracking Sensor Module IR Line Patrol For Arduino DIY Smart Robot Car
[33058494583] 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
