1. When the module detects an
obstacle in front of the signal , the green
indicator light on the board level , while
low-level continuous output signal OUT port ,
the module detects the distance 2 ~ 30cm,
detection angle 35 °, the distance can detect
potential is adjusted clockwise adjustment
potentiometer to detect the distance increases ;
counterclockwise to adjust the potentiometer to
reduce the detection distance .
2 .active infrared sensors to
detect the reflected , and thus the shape of the
reflectivity of the target detection range is
critical . The minimum detection distance which
black , white maximum ; small objects from a
small area , a large area from the Grand .
3 . the output port OUT
sensor module can be directly connected to the
microcontroller IO port , you can directly drive
a 5V relay ; Connection : VCC-VCC; GND-GND;
OUT-IO
4 .using the comparator
LM393, stable ;
5 .can be used for 3-5V DC
power supply modules . When the power is turned
on, the red power

Specifications:
6. with the screw holes of
3mm , easy fixed installation ;
7. board size : 3.1CM * 1.5CM
8. each module shipments
comparing the threshold voltage has been
adjusted by the potentiometer is good , not
exceptional circumstances, do not arbitrarily
adjust the potentiometer.
9. VCC: external 3.3V-5V
voltage (can be directly connected to 5v MCU and
3.3v MCU)
10. GND: GND External
11. OUT: small board digital
output interfaces (0 and 1) |
