Product Description

DESCRIPTION:

• The sensor module has strong ability to adapt to ambient light. It has a pair of infrared transmitting and receiving tubes. The transmitting tube emits infrared light of a certain frequency.
• Signal output interface outputs a digital signal (a low-level signal). The detection distance can be adjusted by the potentiometer knob. The effective range is 2 to 30cm and the working voltage is 3.3V.5V.
• The sensor’s detection distance can be adjusted by a potentiometer, has small interference, is easy to assemble, and is easy to use.

FEATURES:

• 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 – 30 cm, detection angle 35 degree, the distance can detect potential is adjusted clockwise adjustment potentiometer, detects the distance increases. Counterclockwise adjustment potentiometer, reducing detection distance.
• Infrared reflection detection: 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.
• Connect to: 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.

Usage:

• Can be applied for 3-5V DC power supply modules.
• When the power is turned on, the red power indicator light.
• Using the comparator LM393.
• Each module has been shipped threshold comparator voltage adjusted by potentiometer good, non-special case, do not adjustable potentiometer.

SPECIFICATION:

• Interface:

1. VCC: external 3.3-5 voltage (can be directly connected to 5v MCU and 3.3v MCU)

2. GND: GND external

3. OUT: small board digital output interfaces (0 and 1) Connection : VCC-VCC; GND-GND; OUT-IO Board size: 3.1 x 1.5 cm/ 1.22 x 0.59 inch, with the screw holes of 3mm, easy fixed installation
