IR Speed Sensor Module _Computing For Arduino

Description

• 1. The use of imported groove coupler sensor
• 2. The groove width of 5mm
• 3. Output status indicator, the lamp off output high, output low lights.
• 4. Obscured, output high; unobstructed, output low
• 5. The comparator output signal clean, good waveform, driving ability, more than 15mA
• 6. The working voltage of 3.3V-5V
• 7. The output format: digital switching outputs (0 and 1)
• 8. A fixed bolt holes for easy installation
• 9. Small plates PCB size: 3.2cm x 1.4cm
• 10. Using a wide voltage LM393 comparator

• 1. Module slot unobstructed when the receiver turns on, the module DO output low, while blocking, DO output high;
• 2. Can be connected to the relay module DO composition limit switch functions, the buzzer may be connected to the active module composed alarm.
