Specification:
Interface. 1:
Using the comparator : LM393 1.
VCC: external 3.3-5 voltage (can be directly connected to 5v MCU and 3.3v MCU)
GND: GND external
OUT: small board digital output interfaces (0 and 1)
Connection : VCC-VCC; GND-GND; OUT
Board size: 3.1 x 1.5 cm/ 1.22 x 0.59 inch, with the screw holes of 3mm, easy fixed installation
Package includes:
10 x Infrared obstacle avoidance module
Usage.
1, when the module detects the signal of an obstacle ahead, the green indicator on the board level lights up, while the OUT port continuous low-level signal output, the module detection distance of 2-30 cm, detection angle of 35 degrees, can detect the distance potential for clockwise adjustment of the potentiometer, the detection distance increases.
Counterclockwise adjustment of the potentiometer, the detection distance decreases.
2, the sensor uses active infrared reflection detection, the target's reflectivity and shape is therefore the key to the detection distance.
The black detection distance is the smallest, white detection distance is the largest; small object distance is small, large area distance
3, the output port OUT of the sensor module can be directly connected to the microcontroller, but also directly drive 5V relays; connection. vcc-vcc; GND-GND; OUT.
