IR Sensor module has great
adaptive capability of the ambient light, having a pair of infrared
transmitter and the receiver tube, the infrared emitting tube to emit a
certain frequency, encounters an obstacle detection direction
(reflecting surface), infrared reflected back to the receiver tube
receiving, after a comparator circuit processing, the green LED lights
up, while the signal output will output digital signal (a low-level
signal), through the potentiometer knob to adjust the detection
distance, the effective distance range 2 ~ 10cm working voltage of
3.3V-5V. The detection range of the sensor can be adjusted by the
potentiometer, with little interference, easy to assemble, easy to use
features, can be widely used robot obstacle avoidance, obstacle
avoidance car assembly line count and black-and-white line tracking and
many other occasions.
Features of IR Sensor Module:-
the module detects obstacles in front of the signal, the circuit board
green indicator light level, while the OUT port continuous output
low-level signals, the module detects a distance of 2 ~ 10cm, detection
angle 35 °, the detection distance can be potential adjustment with
adjustment potentiometer clockwise, the increase in detection distance;
counterclockwise adjustment potentiometer, the detection distance
sensor active infrared reflection detection, target reflectivity and
shape of the detection distance of the key. The black minimum detection
range, white maximum; small area object distance is small, a large area
from the large.
sensor module output port OUT can be directly connected with the
microcontroller IO port can also be driven directly to a 5V relay;
Connection: VCC-VCC; GND-GND; OUT-IO.
- The comparator using LM393, stable.
- 3-5V DC power supply module can be used. When the power is turned on, the red power LED is lit.
- With the screw holes of 3mm, easy to install.
- Board size: 3.1CM * 1.5CM.
module in the delivery has threshold comparator voltage adjustable via
potentiometer, special circumstances, please do not adjust the
- VCC external 3.3V-5V voltage (can be directly connected with the a 5v microcontroller and 3.3v microcontroller).
- GND external GND.
- OUT board digital output interface (0 and 1).
