IR Sensor

Description

• When the module detects an obstacle in front of the signal , the green indicator light on the board level , while low-level continuous output signal OUT port , the module detects the distance 2 ~ 30cm, detection angle 35 °, the distance can detect potential is adjusted clockwise adjustment potentiometer to detect the distance increases ; counterclockwise to adjust the potentiometer to reduce the detection distance
• Active infrared sensors to detect the reflected, and thus the shape of the reflectivity of the target detection range is critical. The minimum detection distance which black , white maximum ; small objects from a small area , a large area from the Grand
• The output port OUT sensor module can be directly connected to the microcontroller IO port , you can directly drive a 5V relay Connection : VCC-VCC; GND-GND; OUT-IO

Specification

• Connection : VCC-VCC; GND-GND; OUT-IO
• Using the comparator LM393, stable
• Can be used for 3-5V DC power supply modules. When the power is turned on, the red power indicator light
• With the screw holes of 3mm , easy fixed installation
• Board Size : 3.1CM * 1.5CM / 1.22 * 0.59"
• Each module shipments comparing the threshold voltage has been adjusted by the potentiometer is good , not exceptional
• circumstances, do not arbitrarily adjust the potentiometer
• Interface Description (3-wire):
• 1. VCC: External 3.3V-5V 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)
