Specification

Description

An Infrared Obstacle Avoidance IR Sensor Module, particularly one with an "Active Low" output, is a type of sensor commonly used in various applications, including robotics and automation. This sensor is designed to detect obstacles or objects in its vicinity using infrared (IR) light.

Here's a breakdown of its key components and how it works:

Infrared Emitter and Receiver: The module typically contains an IR emitter (often an IR LED) and an IR receiver (usually a photodiode or phototransistor). The emitter emits infrared light, and the receiver detects the reflected infrared light.

Active Low Output: "Active Low" means that the sensor's output signal goes low (or near 0V) when it detects an obstacle. In other words, the sensor's output is normally high (at a higher voltage level) and drops to a lower voltage level when an obstacle is detected.

Obstacle Detection: When there's no obstacle in the sensor's line of sight, the IR light emitted by the emitter isn't reflected back to the receiver, so the receiver's output remains high. However, when an obstacle or object is present in front of the sensor, it reflects the IR light back to the receiver, causing the receiver's output to go low.

Digital Output: The output of this type of sensor is typically digital, making it easy to interface with microcontrollers or other digital electronics. You can connect the sensor's output pin to a microcontroller's digital input pin to detect obstacles and trigger appropriate actions.

Applications:

Obstacle Avoidance: In robotics, these sensors are often used on mobile robots to detect obstacles in their path and navigate around them.

Object Detection: They can be used in automated systems to detect the presence or absence of objects on a conveyor belt or in a specific location.

Proximity Sensing: These sensors can be used to determine if an object is within a certain distance of the sensor.

Gesture Recognition: In some applications, they are used to detect hand gestures or motion.

Security Systems: They can be part of security systems to detect movement or intrusion.

To use an Active Low IR Sensor Module, you typically connect its output pin to a digital input pin on a microcontroller or another control system. You then monitor the sensor's output state to detect obstacles or changes in proximity, allowing you to take appropriate actions in your application.

detects at max 10 cm

It works well, however hardly beyond 10 cm unless you approach a mirror or a reflective metal. For the rest, excellent value for money.

Good product

These work well, but they do draw a lot of current. I had all ten plugged in and my little power supply got very hot.

Great Inexpensive Sensor to use with Arduino

Had no issue hooking up or using these sensors with an arduino. Made a couple of line follower robots that worked very well.

2nd Purchase

Ive bought these from kitsguru before. I had absolutely no problems with the first batch, so I bought from them again. So far, no problems with these, either.
