Description

Circuit schematic like in Infra Red Sniffer Based on the IR Sensor Module TSOP1838 from Vishay for you. This circuit is the front-end of IR Sniffer when you want to decode and encode the data from IR transmitter. This circuit will capture the IR code and also can retransmitte the date if need.

According Electroschematics site describe that the design is based on the IR sensor module TSOP1838 from Vishay, it inherently supports the NEC format but can be easily extended to multiple IR data formats with necessary modifications. The TSOP1838 is a miniaturized IR receiver module with a PIN diode and preamplifier assembled on lead frame; the epoxy package is designed as an IR filter. The demodulated output signal can directly be decoded by most microprocessors. 

The IR receiver module is represented here by IRRX, powered from a 5-Vdc supply. An infrared emitter (IRED) is available for changing the hardware as an IR encoder. LED1 indicates the IR signal activity but may be omitted together with R2.
