Arduino Ir Receiver 3 Pin 38khz Receiver

The LFN – series are miniaturized receivers for infrared remote control systems. PIN diode and preamplifier are assembled on lead frame, the epoxy package is designed as IR filter. 
The demodulated output signal can directly be decoded by a microprocessor. TSOP1238 is the standard IR remote control receiver series, supporting all major transmission codes. 

Features:

• Photo detector and preamplifier in one package
• Internal filter for PCM frequency
• TTL and CMOS compatibility
• Output active low
• Improved shielding against electrical field disturbance Suitable burst length ≥10 cycles/burst
•  Low power consumption
• High immunity against ambient light
• Continuous data transmission possible (800 bit/s)
