The infrared barrier Module; Obstacle Avoidance car obstacle avoidance sensor; identification of black-and-white line; distance adjustable
One module description
The sensor module is the ability to adapt to the environment light, and having a pair of infrared transmitter and the receiver tube, emitting infrared ray tube emits a certain frequency, when the detected direction, encounters an obstacle (reflection surface), the infrared reflected back is received tube receiving after a comparator circuit processing, the green light will be lit, the signal output interface output digital signal (a low-level signal), via a potentiometer knob to adjust the detection distance, the effective distance range of 2 to 80cm, operating voltage of 3.3V-5V. Detection range of the sensor can be adjusted via potentiometer, with little interference, easy assembly, easy-to-use features, can be widely used in robot obstacle avoidance, obstacle avoidance trolley, assembly line count, and black and white line tracking and many other occasions.
Two module parameter description
When the module detects obstacles in front of signal, the circuit board green indicator light level, while OUT port sustained output low-level signals, the module detects the distance to 60cm, detection angle of 35 °, the detection distance by potentiometer adjust, adjust the potentiometer clockwise, the detection distance increases; counterclockwise adjusts the potentiometer, the detection distance is reduced.
2, the sensor active infrared reflectance probe, therefore, the reflectance and the shape of the target is the key of the detection distance. Black detection range of the smallest white maximum; small area of the object distance is small, a large area from the Grand.
3, the sensor module output port OUT can be directly connected with the single-chip IO can be, but also can directly drive a 5V relay; Connection: VCC-VCC; GND-GND; OUT-IO
Comparator LM393, job stability;
5, to be used in 3-5V DC power supply for the module power supply. When the power is turned on, the red power indicator lights;
6, with the screw holes of 3 mm, easy fixed installation;
7, the board size: 3.1CM * 1.5CM
Each module in the delivery of the threshold comparator voltage through the potentiometer adjustment, non-special, Do not adjustable potentiometer.
Module interface specification (3-wire)
1 VCC external 3.3V-5V voltage (can be directly connected to the 5v microcontroller and 3.3v microcontroller)
2 GND external GND
3 OUT board digital output interface (0 and 1)
