Arduino Infrared proximity switch module

overview

Arduino infared proximity switch module is a reflection-type photoelectric sensor which integrates transmitting and receiving infared beams function. Infrared proximity switches work by sending out beams of invisible infrared light. A photodetector on the proximity switch detects any reflections of this light. These reflections allow infrared proximity switches to determine whether there is an object nearby.

technical parameters

• Voltage :DC 5V
• Current  :100mA
• Type :DC 3 Wire NPN-NO (Normal Open)
• Sensory Distance: 3-80 cm adjustable
• Sensory distance regulator and output indicator light on product back
• Control signal level:
• High：2.3V≤Vin≤5V
• Low：-0.3V≤Vin≤1.5V

Usage

When sensor detect object, it output 0V.
