LESSON 7 – REMOTE CONTROL WITH IR RECEIVER MODULE OF ARDUINO

The Keyes IR receiver is used in this project for infrared remote control. With low power consumption and an easy to use package, it mates well with embedded electronics and can be used with common IR remotes. The TSOP18 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. The main benefit is the reliable function even in disturbed ambient and the protection against uncontrolled output pulses.
