5PCS IR Infrared Obstacle Avoidance Sensor Module for Arduino Car Robot 3-wire Reflective Photoelectric New Porcelain
The sensor module light is adaptable to the environment, it has a pair of infrared
transmitting and receiving tube, tube infrared emitting a certain frequency.
when detecting direction meet with obstacles(reflecting surface), reflected infrared
receiving tube, after the comparator circuit processing, green indicator will light up,
at the same time signal output interface and output digital signal (a low level ov)
distance range 2-30 cm, the working voltage of 3.3 V to 5 V The detection range ve
of the sensor can through the potentiometer to adjust and have small interference
easy to assemble, easy to use, etc, can be widely used in robot obstacle avoidance,
obstacle avoidance car, line count and black and white line tracking and so on many occasion
Product performance
1. when signal module without obstacles ahead, the OUT port(5V) output level
continuously. When the module detects obstacles ahead signal, circuit board on the
green light is lit, the OUT port at the same time Continuous output low level (0 v)
signal, the detection module from 2-30 cm, 35 Angle detection, detection Distance
can be adjusted through the potentiometer, clockwise adjust potentiometer,
detection distance increases Counter-clockwise tuning Potentiometer, reduce the
detection distance
2. Active infrared reflection detecting sensor, therefore the reflectivity and shape of
the target is the key of the detection range. One black minimum detection range,
hite biggest; Small area of the object distance, large distance
3. The sensor module output port OUT can be directly connected to the
microcontroller 10 port, can also direct drive a 5V relay, Connection mode
the Vcc- Vcc GND- GND The OUT-IO
4, the comparator USES the LM393, work stability.
5, can use 3. 3 V to 5 v dc power to power supply module. When power on, the red
power indicator Lights up
Directions for use
1. VCC external 3. 3V to 5V voltage(which can be directly connected to
5V microcontroller or 3.3 V microcontroller)
2. The GND external GND
3. The OUT small plate digital output interface(0 and 1)
Description
1. can detect the brightness and intensity of ambient light
2. sensitivity adjustable (shown in blue digital potentiometer control)
3. working voltage of 3.3 V - 5 V
4. output form:
(a) analog voltage output
