Vishay TSOP IR Receiver Modules for Remote Control Systems - Vishay TSOP31240, A miniaturised infrared receiver module with a carrier frequency of 40kHz that has been designed for remote control systems.
A PIN diode and a preamplfier are assembled on a lead frame with the epoxy package acting as an IR filter.
The demodulated output signal can be directly connected to a microprocessor for decoding.
The module is optimised to suppress most spurious pulses from energy saving lamps such as CFLs.
