module description:
The ambient light sensor module adaptable, having a pair of infrared transmitter and receiver, launch tube infrared emission of a certain frequency, when detecting the direction of an obstacle (reflecting surface), reflected infrared receiver tube is received, after the comparator circuit processing, the green indicator light, while the signal output interface output digital signal (a low-level signal) can be detected from the knob to adjust the potentiometer, the effective distance range 2 ~ 30cm, working voltage is 3.3V- 5V. Detection range of the sensor can be adjusted via a potentiometer, with a small interference, easy to assemble, easy to use features, it can be widely used in robot obstacle avoidance, avoidance car, count lines and black and white line tracking and many other occasions.
Two module Parameter Description
1 When the module detects obstacles in front of the signal, the green LED is lit on the board level, while continuing OUT port outputs a low level signal, the module detection distance 2 ~ 30cm, detection angle 35 °, the detection distance by potentiometer was adjusted, adjust potentiometer clockwise, to increase the detection distance; counterclockwise to adjust potentiometer, reduce the detection distance.
2, the sensor active infrared reflection detection, so the target reflectivity and shape is the key to the detection distance. Wherein the black detection range minimum, maximum white; small area of small objects from a large area from the great.
3, the sensor module output port OUT port can be directly connected to the microcontroller IO, can directly drive a 5V relay; Connection: VCC-VCC; GND-GND; OUT-IO
4, comparators LM393, stable;
5, can be used for 3-5V DC power supply module. When the power is turned on, the red power indicator lights;
6, with screw holes 3mm, easy fixed installation;
7, circuit board size: 3.1CM * 1.5CM
8, each module has been shipped threshold comparator voltage adjustable by potentiometer good, non-special case, do not adjustable potentiometer.
Three – module interface specification (3-wire)
1 VCC 3.3V-5V external voltage (can be directly connected to the 5v and 3.3v microcontroller MCU)
2 GND External GND
3 OUT small board digital output interface (0 and 1)
Four shipping list
Barrier wall as shown in Figure 1 a sensor module
