Ultra-Small Infrared Digital Obstacle Avoidance Sensors w/ Adjustable Potentiometers (3.8~5.5V)

Ultra-Small Infrared Digital Obstacle Avoidance Sensors w/ Adjustable Potentiometers (3.8~5.5V)

Short Description:

  • Sensor initiative emit infrared light detection, according to the reflection, if detect an obstacle, the OUT pin output 0,   otherwise1.
  • Operating voltage: 3.8~5.5V
  • Operating current (5V): 6mA (Typical)
  • Input and output signals (3 lines): VCC GND OUT
  • With precision adjustable potentiometers, adjustment range is from 3cm to 100cm.

Detailed Description:

Digital signal output, the sensor containing the necessary modulation and demodulation, the logic processing.

How it works: the sensor active emits infrared light, reflected light detection detected obstacles OUT pin outputs 0, otherwise 1.
Operating voltage: 3.8v-5.5v
Operating current (5V): typical current 6mA

Input and output signals (3 lines):
VCC GND OUT

GND, VCC is the power supply VCC of the range is 3.8V to 5.5V

How to turn precision adjustable potentiometer board, based on the use of environmental regulation. Adjustment range from 3cm-100cm. Because it is a reflection principle associated with a specific target of reflection can be adjusted according to the situation.

The circuit board has a red LED to detect the obstacles glow OUT output sustained low. Accessibility OUT output voltage level.

Obstacle detection time (effective detection range from the accessible target to be obstacles or barriers disappear into the obstacles goal): <= 21ms

Sensor active infrared reflectance probe, therefore, the reflectance and the shape of the target is the key of the detection distance, wherein the minimum distance of the black detection, white maximum; small area of the object distance is small, the distance to a large area.
Here is the actual test detection range:

Detection range (test environment, indoor, maximum power voltage 5v, power consumption 6.5ma):

1 white walls: 100cm

2. IBM computer cover: 20cm

3.1 finger: 18cm

4 palm: 30cm

5. A transparent ballpoint pen: 20cm

6. transparent ballpoint pen can sensitively detect
