Bulk buy success

Ordered 50 units for our workshop. Every single one worked out of the box. Consistent performance across the batch makes these ideal for classroom settings.

Reliable IR Reception

I've tested this against several TV remotes and it decodes signals perfectly. The library support for popular microcontrollers makes integration a breeze. Highly recommended for DIY electronics.

Compact and Efficient

The small form factor fits easily into tight spaces on my custom PCB. Power consumption is low, which is great for battery-operated projects. No issues with interference so far.

Perfect for Arduino Projects

This sensor works flawlessly with my Arduino Uno. I used it to build a custom remote control for my robot car, and the response time is incredibly fast. The 38kHz frequency filters out ambient light noise effectively.

Great value for education

Bought a pack for my son's science club. They are easy to wire up and durable enough for kids handling them. One unit had a slightly loose pin, but overall excellent quality for the price.

Good sensitivity

Works well within the stated range. I noticed the range drops slightly if there is direct sunlight hitting the sensor, but that is expected for IR technology. Overall very satisfied.

5 FAQ

Q: How many pins does this module have?

A: The module features a standard 3-pin interface: VCC (Power), GND (Ground), and OUT (Signal Output).

Q: Can this module work with a 3.3V logic level microcontroller?

A: Yes, this module operates comfortably within the 3.3V to 5V range, making it fully compatible with 3.3V logic systems like the ESP32 or Raspberry Pi.

Q: Is this suitable for outdoor use?

A: It can be used outdoors, but direct sunlight contains high levels of infrared which may interfere with the signal. We recommend shielding the sensor from direct sun for optimal performance.

Q: What is the maximum angle of reception?

A: The sensor has a receiving angle of approximately ±45 degrees. For best results, ensure the transmitter is pointed somewhat directly at the receiver.

Q: Does this come with a library for Arduino?

A: While the hardware itself does not include software, it is fully compatible with the standard IRremote library available in the Arduino Library Manager.
