Photo Module for different carrier frequencies
A Vishay Telefunken’s TSOP1156 photo module should be used for Sejin 4PPM wireless products with
56KHz carrier frequency as an IR detector. A Vishay Telefunken’s TSOP1138 photo module should be
used for Sejin 4PPM wireless products with 38KHz carrier frequency as an IR detector.
The data sheets for the components are available on below web page.

Note: In order not to reduce the sensitivity of the photo module by power line noise or ripple, the 47uF
capacitor C1 on the schematic diagram must be placed as close as possible to the GND pin and the
VCC pin of the photo module.
