Additional Details

The TSOP1133 operates effectively within a supply voltage range of 2.5 V to 5.5 V, making it suitable for a variety of power supply configurations. The device's epoxy package is designed to filter out unwanted IR signals, ensuring that only the intended 33 kHz carrier frequency is processed. The output of the TSOP1133 is active low, meaning that it outputs a low signal when an infrared signal of the correct frequency is detected.
