Reliable components
Bought multiple kits for our workshop. All receivers tested working. No dead pixels on the IR LED.

Solid performance
Does the job for IR communication. Wish it came with a sample code sheet, but easy to find online.

Easy to integrate
I was worried about wiring but the pinout is standard. Successfully decoded signals using my STC89C52.

Good value kit
Used this for a custom car MP3 controller. Range is decent indoors. One button on the remote felt a bit stiff but works fine.

Perfect for my 51 MCU project
Works exactly as described. The IR receiver is sensitive and the remote buttons are responsive. Great for learning IR protocols.
Q: Does this work with 3.3V logic?
A: Yes, the module supports operating voltage from 3.3V to 5V DC.
Q: What are the pin definitions for the receiver?
A: Usually VCC, GND, and OUT. Please refer to the datasheet included in the package for specific orientation.
Q: What is the effective range indoors?
A: Typically around 8 to 10 meters in direct line of sight without strong interference.
Q: Can I use this with an Arduino instead of 51 MCU?
A: Yes, it is compatible with most microcontrollers that support digital input decoding.
Q: Is there a library for Keil C51?
A: We do not provide specific IDE libraries, but the protocol is standard NEC which is widely documented.
