Frequently Asked Questions

What is the operating voltage range for the HS-S23P module?

The HS-S23P module operates from 2.5V to 5.5V DC, making it directly compatible with both 3.3V and 5V microcontroller logic levels without requiring a level shifter.

How do I interface the HS-S23P with an Arduino microcontroller?

Connect the module's V pin to Arduino 5V, G to GND, and the S (signal) pin to any digital input pin. The output is active-low, meaning the pin goes LOW when a valid 38 kHz IR signal is detected.

What does '38KHz decoding' mean for this receiver?

It means the module is tuned to receive infrared signals modulated at a 38 kHz carrier frequency, which is the standard for most TV, audio, and air conditioner remote controls. It demodulates this signal and outputs the underlying digital command code.

Can this module be used in bright sunlight or well-lit rooms?

Yes, the HS-S23P features internal filtering designed for high immunity to ambient light interference, allowing for reliable operation in typical indoor lighting conditions. For extreme direct sunlight, some shielding may be beneficial.
