  • 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


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

Bendable IR detector/emittors. Good value for the money.

Install on HO layout. These work great with a Radpberry Pi. Only issue was track lighting giving off IF Red and tripping the sensors. Change bulbs to LEDs and solved the issue. Fun working with them. Used to drive signals on the layout

As described by someone else, action is the reverse of the description and artwork + and - are reversed for the sensor, at least. With these shortcomings, still a value for the price.

3 units out of 10 are not functional and not getting any output even the power LED is on, fortunately I only need 6 and extra was spare parts.

Features:1, When the module detects an obstacle in front of the signal, the green indicator lights up at the board level and the OUT port keeps the signal output low, the module detects a distance of 2-30 cm,detection angle 35 °, adjusted clockwise adjustment potentiometer, distance can detect potential, detect increasing distance. Adjusted counterclockwise potentiometer, shortened detection distance.2, active infrared reflection detection of sensor, reflectance of target, therefore shape is critical detection distance.Minimum detection distance is black, white, maximum.

I mean...I don't know if they correct it after the customer who found the previous issue, man! They work ok, just short range. Nothing else to dislike abt these amazing little Ir sensors😎. Great for how much I paid for them. I tried to come up with my own built, man! It's time consuming if you are a guy like me, no special pcbs, oven, tools. Yeah, I love these little guys. They get the job done! I'll 100% tell you get them. I also made an interesting discovery that you can increase the range by adding 1 to 5 sensors in //. 3IRs was the ideal range for me, abt 24" range. You can try that, or maybe one has better range😁It's abt 7" for detection, which is great for my robot mower ege sensor.😁

Was quite impressed with the units. Each unit was packaged and sealed in a static bag and all were over packed in one bag. Before using the units I tested each one and everyone of the sensors worked. I am using them at 4.5Vdc and they are maxing out sensing objects at 10-13 cm. The units have an adjustment pot so you can vary the distance and two LED's, one to indicate power and the other when an object is sensed will light. I found this helpful in fine tuning the sensor. I visually inspected the modules and they all looked to be well manufactured especially for the price.

Funziona molto bene, ma punta massimo a 5 cm in tutte le condizioni migliori ! Non lo restituisco perché alla fine dei conti posso utilizzarlo per altri scopi ! Niente non lo consiglio per grandi distanze chiaramente !

Funziona bene, comunque difficilmente oltre i 10 cm a meno di non avvicinare uno specchio o un metallo riflettente.Per il resto ottimo rapporto qualità prezzo.
