Infrared Reflectance Sensor TCRT5000 Obstacle Avoidance Monitoring Sensor Tracking Module

baby description
1 sensor adopts TR5000, high sensitivity
2 sensitivity adjustable digital potentiometer adjustment (blue)
3 modules can sense blocks from 0 to 3 cm
4-5 V working voltage 3.3 V
5 output form output analog voltage (0 to 5 v)
B Digital switching outputs (0 and 1)
6 There are fixing bolt holes for easy installation
7 Small board PCB size: 3.5cm*1.5cm
8 power indicator (red) and digital switch output indicator (green)
9 The comparator adopts LM393 chip, which works stably
Three small board interface specification wire (4)
1 VCC External 3.3 V to 5 V
2 GND External GND
3 DO small board digital output interface (0 and 1)
4 small AO board analog output interfaces (0 to 5V)
four instructions
1 module can be used for intelligent tracking car obstacle avoidance, material detection, color detection
2 When the light-emitting or blocking distance of the module is greater than the set threshold, DO outputs a high level, and when the blocking distance of the module is less than the set threshold, the module D0 outputs a low level;
The digital output D0 of the 3 small boards can be directly connected to the single-chip microcomputer, and the high and low levels are detected by the single-chip microcomputer, so as to detect whether the module is triggered;
4 small board digital output DO can directly drive our relay module, which can form a photoelectric switch;
The 5 small board analog outputs can connect the AO and AD modules together, and through AD conversion, the distance between the can module and the obstacle can be obtained.
