DESCRIPTION

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.

indicator light:

with the screw holes of 3mm, easy fixed installation.

board size: 3.1CM * 1.5CM.

Interface Description (3-wire):

VCC: external 3.3V-5V voltage (can be directly connected to 5v MCU and 3.3v MCU).

GND: GND External.

OUT: small board digital output interfaces (0 and 1).
