Infrared Digital Obstacle Avoidance Sensor super Small 3-100cm Adjustable Current 6mA

Module description
The sensor module has strong adaptability to ambient light and is basically not affected by external light. There are many adjustable potentiometers on the board, which can be adjusted according to the use environment. The adjustment range is from 3cm to 100cm. Because it is the principle of reflection, with specific The target of the reflection is related and can be adjusted according to the situation.
There is a green LED on the board, which emits light when an obstacle is detected. The OUT output continues to be low. Accessibility is the OUT output continues to be high.

Module interface
VCC external DC3.8V-5.5V power supply positive (can be directly with 5v microcontroller)
GND external DC3.8V-5.5V power supply negative
OUT small board digital output interface (0 and 1)

Module parameter
Working principle: The sensor actively emits infrared rays and detects according to the reflected light. If an obstacle is detected, the OUT pin outputs 0, otherwise 1.
Working voltage: 3.8v-5.5v
Working current (5V): typical current 6ma

Obstacle detection time (from obstacle-free target to obstacle in effective detection range, or obstacle to obstacle disappearing): <=21ms

The sensor actively detects infrared reflection, so the reflectivity and shape of the target are the key to the detection distance. The black detection distance is the smallest and the white is the largest; the small area object has a small distance and the large area distance is large.
The following is the detection distance of the actual test:
Detection distance (test environment, indoor, maximum power, voltage 5v, power consumption 6.5ma):
1. White wall: 100cm
2. IBM black computer cover: 20cm
3. 1 finger: 18cm
4. Palm: 30cm
5. A transparent ballpoint pen: 20cm
A transparent ballpoint pen can detect sensitively.

Module characteristics
1. Ultra-miniature, and designed with mechanical mounting holes.
2. Low power consumption, wide working voltage range. The transmitted signal uses modulated signal, the distance is long, the anti-interference is good, and it can work under outdoor direct sunlight (the distance will be shorter).
3. The distance is adjustable from 3cm to 100cm.
4. Obstacle avoidance uses window technology to avoid the critical section problem, the sensor works very stable, the user directly uses the output signal, no need to consider the signal jitter problem.
