TSOP1838 – Infrared Sensor

This is IR Receiving Head VS1838B Remote Control Receiver. The 1838 is miniaturized infrared receivers for remote control and other applications requiring improved ambient light rejection. The separate PIN diode and preamplifier IC are assembled on a single lead frame. The epoxy package contains a special IR filter. This module has excellent performance even in disturbed ambient light applications and provides protection against uncontrolled output pulses. Use this IR Receiver Diode – TSOP38238, a simple IR receiver for the infrared remote control of your next project. With low power consumption and an easy-to-use package, it mates well with embedded electronics and can be used with common IR remotes. A PIN diode and a preamplifier are assembled on a lead frame while the epoxy package acts as an IR filter. The demodulated output signal can be directly decoded by a microprocessor.
