TCRT5000 infrared reflectance sensor module โมดูลแทรคเส้น ข้อมูล TCRT5000 infrared reflectance sensor Obstacle avoidance module tracing sensor tracing module sensor adopts TR5000, high sensitivity sensitivity adjustable digital potentiometer to adjust blue) modules can induction block from 0 to 3 cm 5 V working voltage 3.3 V a output form output analog voltage 0 to 5 v) digital switch output 0 and 1) has a fixed bolt hole, convenient installation small board PCB
size: 3.5 cm 1.5 cm power indicator light red and digital switch output indicator light green) comparator USES the LM393 chips, work stability Three small plate interface specifications wire 4) VCC external 3.3 V to 5 V GND external GND DO small plate digital output interface 0 and 1) small AO plate analog output interface 0 to 5 v) Four instructions module can be used to intelligent tracing car obstacle avoidance, material testing, color detection modules in shining or keep out the distance is greater than the set threshold the DO output high level, when the module block distance is less than the setting threshold, module D0 output low level, small plate digital output D0 can be attached directly to the microcontroller, through single chip microcomputer to detect the high and low level, thus to detect whether the modules are triggered, small plate digital output DO can directly drive our relay module, which can be composed of a photoelectric switch, small plate analog output can AO and AD modules are linked together, through the AD conversion, can module are obtained and the obstructions of distance
