1 sensor adopts TR5000, high sensitivity
2 sensitivity adjustable digital potentiometer to adjust (blue)
3 modules can induction block from 0 to 3 cm
4-5 V working voltage of 3.3 V
5 a output form the output analog voltage (0 to 5 v)
B digital switch output (0 and 1)
6 has a fixed bolt hole, the work of the installation
Seven small board PCB size: 3.5 cm * 1.5 cm
8 the power indicator light (red) and digital switch output indicator light (green)
9 comparator USES the LM393 chips, work stability
Three small plate interface specifications wire (4)
1 VCC external 3.3 V to 5 V
2 GND external GND
3 DO small plate digital output interface (0 and 1)
4 small AO plate analog output interface (0 to 5 v)
The module can be 1 2 intelligent tracing car obstacle avoidance, material testing, color detection
2 modules in shining or keep out the short is greater than the set threshold the DO output high level, the when the module block short is less than the setting threshold, the module D0 output low level;
3 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 been the modules are triggered.
4 small plate digital output DO can directly drive our relay module, which can be composed of a photoelectric switch;
5 small plate analog output can AO and AD modules are linked together, through the AD conversion, the can module are obtained and the obstructions of short.
