Additional Details

The TSOP1156 is typically packaged in a through-hole or surface-mount package. It requires a supply voltage of 2.5 V to 5.5 V. The output signal is a digital signal that is low when an IR signal is detected and high when no IR signal is present. It is crucial to consult the datasheet for detailed electrical characteristics, timing diagrams, and recommended operating conditions. Proper filtering of the power supply is essential for minimizing noise and ensuring reliable operation. The module should be shielded from direct sunlight to prevent saturation of the photodiode.
