Product Overview: 
 I produced the M23F Infrared reflection module is a set of infrared transmitter and receiver with integrated circuit components, it contains an internal infrared modulation, coding, launching; after occluder received after reflection, amplification, demodulation, decoding and signal shaping and the output circuit, able to detect non-contact form of 3 meters from the front, still and moving people or things, and the form of high output signal. M23F due to internal use of all-digital CMOS integrated circuit designed, so job stability, excellent performance and reliability, low power consumption, resistance to light interference; widely used in rapid response, high accuracy, long-range automatic detection, automatic alarm and automatic control products; if used for close inspection, can be quickly detected to 0.1 mm below the object. 
 Instructions for use: 
 Output termination test status indicator LED as working with; no reflector (or things) when the LED is off, when a reflector is detected when the LED steady glow. Remove it out until the reflector; module with a variable resistor is used to adjust the monitor distance. Transfer distance increases counterclockwise, a clockwise adjustment decreases the distance. 
 Module terminals marked G to ground terminal, the terminal marked + V to +5 V DC terminals, the terminal marked with S for the signal output terminal. 
 M23F-type infrared reflection detection module, anti-electromagnetic interference of radio waves; anti-natural light, all kinds of lighting and other light interference. Working condition during the day and night in good agreement.
