Eight Road 8 Channel Infrared Detector Tracking Transmission Line Obstacle Avoidance Sensor Module for Arduino Diy Car Robot
 
 
Brief introduction:
This module is to provide intelligent vehicles, robots and other automated machinery of a multipurpose infrared detection system solutionsUsing infrared transmitting and receiving tube of discrete components such as probes, and use the LM339 voltage comparator (joined the delay circuit is more stable) control circuit as the core deviceThis system has a variety of detection function can greatly satisfy the guest all kinds of automatic and intelligent application of small systems
Please pay attention to the current tracing module only single limit comparator, without delay circuitSingle limit comparator, if there is a small input signal Uin near the threshold, the output voltage can produce corresponding jitter (ups)In introducing positive feedback circuit can overcome this shortcomingWe joined the delay circuit, makes the work more stable
 
 
 
 
Features:
Easy to install and easy to use
4 road work individually, without being limited by the number of work
Control board is separated from the probe, the installation position is not restricted
Module height 10 mm or less
Safe working voltage range between 3 v to 6 v
4 road full open working current 30 ma to 55 ma
VCC, GND: power supply terminal
IN (1, 8), OUT: probe connected to the control panel
The OUT1, OUT2  OUT3, OUT4, OUT5, OUT6, OUT7, OUT8 corresponding outputs
LED1, LED2, LED3, LED4, LED5, LED6, LED7, LED8 corresponding output instructions
 
R1, R2, R3 and R4: corresponding voltage regulation
For the open collector output end, onboard 47Kohm pull-up resistor
