Type: Acceleration Sensor
Use: Speed Sensor
semi_Choice: yes
Blue speed sensor:
Widely used in motor speed detection, pulse counting, position limit and so on.
Module features:
1, the use of imported groove coupler sensor, slot width 5mm.
2, output status indicator lamp output high, output low lights.
3, block, output high; no shelter, output low.
4, the comparator output signal clean, good waveform, driving ability, than 15mA.
5, the working voltage of 3.3V-5V
6, the output format: digital switching output (0 and 1)
7, a fixed bolt holes for easy installation
8, small PCB board size: 3.2cm x 1.4cm
9, using a wide voltage comparator LM393
Module for use:
1. module slot unobstructed, receiver tube conduction module DO output low, when blocked, DO output high;
2, DO output interface can be directly connected to the microcontroller IO port, whether the sensor with barriers, such as the motor speed can be detected with the motor encoder.
2. DO module can be connected to relays, limit switches and other functional composition, and to be connected with active buzzer module, consisting of alarm.
Product wiring instructions:
1, VCC positive power supply 3.3-5V
2, GND power supply is negative
3, DO TTL switching signal output
4, AO this module does not work
Black speed sensor:
Widely used in motor speed detection, pulse counting, position limit, etc.
Module features:
1, using imported slot type optocoupler sensor
2. The groove width is 10mm.
3. There is an output status indicator, the output high level light is off, and the output low level light is on.
4, there is occlusion, output high level; no occlusion, output low level.
5, the comparator output, the signal is clean, the waveform is good, the driving ability is strong, more than 15mA.
6, working voltage 3.3V-5V
7, output form: digital switch output (0 and 1)
8, with fixed bolt holes for easy installation
9, small board PCB size: 2.3cmx2cm
10. Use a wide voltage LM393 comparator
Module instructions:
1. When there is no occlusion in the module slot, the receiving tube is turned on, and the module DO outputs a low level. When occluding, the DO outputs a high level;
2. The module DO can be connected to the relay to form a limit switch and other functions. It can also be connected to the active buzzer module to form an alarm.
