Opis parametara jednog modula

   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.

Opis parametara dva modula

• 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.
• 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.
• 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;
• To be used with 3-5V DC power supply for the module power supply. When the power is turned on, the red power indicator lights;
• With the screw holes of 3 mm, easy fixed installation;
• 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.
