## Description

Feature: 1, When the module detects an obstacle in front of the signal, the green indicator lights on the board level, while the OUT port sustained low signal output, the module detects the distance 2 ~ 30cm, detection angle 35 °, the distance can detect potential is adjusted clockwise adjustment potentiometer, detects the distance increases; counterclockwise adjustment potentiometer, reducing detection distance. 2, The sensor active infrared reflection detection, target reflectivity and therefore the shape is critical detection distance. Where the minimum detection distance black, white, maximum; small objects away from a small area, a large area from the Grand. 3, the sensor module output port OUT port can be directly connected to the microcontroller IO can also be directly drive a 5V relay; Connection: VCC-VCC; GND-GND; OUT-IO 4, comparators LM393, stable; 5, the module can be 3-5V DC power supply. When the power is turned on, the red power indicator lights; 6, with the screw holes 3mm, easy fixed installation; 7, board size: 3.2CM * 1.4CM 8, each module has been shipped threshold comparator voltage adjusted by potentiometer good, non-special case, do not adjustable potentiometer. PIN Description: 1 VCC 3.3V-5V external voltage (can be directly connected to 5v and 3.3v MCU MCU) 2 GND GND External 3 OUT small board digital output interface (0 and 1) Package Includes： 10 * IR Infrared Obstacle Avoidance Sensor Module

## Features

- Can be widely used in robot obstacle avoidance, obstacle avoidance car, line count, and black and white line tracking and so on.
- The effective distance range of 2 ~ 30cm, the working voltage of 3.3V- 5V

## Questions & Answers

**Q: Seems to work, but both the power led and signal out led are red, not green.  is this a new revision or do i have something hooked up wrong?**
A: Mine are red, too.  And they work just fine.  No, I don't think you have anything hooked up wrong.

**Q: I am looking for a sensor that can be hidden under a plastic surface, would this be able to detect though a sheet of acrylic?**
A: Not sure about a clear sheet.   I thought I had a piece and I would give it a try but I did not.   I did have a sheet of anti-glare and it did set it off so that material clarity will definitely not work.

**Q: do this only do digital reading and not analog value?**
A: Yes.  Its only digital.  There are similar devices with analog interfaces such as a QRE1113.

**Q: Any way to get a real spec sheet?  the details on this page are incomplete and/or wrong.**
A: I didn't find a real spec sheet
