Perfect for Arduino Projects
This sensor module worked flawlessly with my Arduino Uno. The 38kHz frequency is standard for most TV remotes, making it easy to decode signals. Great value for the price.

Good range, easy to wire
I used this for a line-following robot project. The range is decent indoors, about 8 meters in my tests. Wiring was straightforward with the labeled pins.

Works as described
My son used this for his science fair project. It was easy to set up and the LED indicator helps visualize when a signal is received. One star off because the header pins were slightly bent upon arrival.

Great for learning IR communication
Bought this for a university project on infrared communication protocols. Documentation online is plentiful, and the module responds instantly to remote commands.

Excellent sensitivity
The sensitivity adjustment via the potentiometer on similar models isn't here, but the fixed sensitivity is actually quite good. No false triggers detected during testing.

Reliable and Compact
Very compact design fits well into tight spaces on my custom PCB. Signal reception is stable even under fluorescent lighting which usually causes interference.
Q: Can this module work with a 5V power supply?
A: Yes, this module supports a voltage range of 3.3V to 5V DC, so it is fully compatible with 5V systems like the Arduino Uno.
Q: Can I use this to transmit signals or only receive?
A: This specific module is designed primarily as a receiver. For transmission, you would need a separate IR LED transmitter component, though some kits bundle both.
Q: Is the output signal active high or active low?
A: The output is typically active low, meaning the pin goes to LOW (0V) when an infrared signal is detected and stays HIGH (VCC) otherwise.
Q: Does this come with example code for Raspberry Pi?
A: While the package does not include a physical manual with code, we provide a link to a GitHub repository with Python examples for Raspberry Pi in the product description.
Q: What is the maximum operating distance?
A: Under ideal indoor conditions with a standard IR remote, the effective range is approximately 10 meters. Outdoor sunlight may reduce this range significantly.
