Infrared Receiver Module: A Smart Lighting Solution for Modern Homes
In today's smart home era, Infrared Receiver Modules have become essential components for lighting control systems. These compact devices allow wireless remote operation of lights, offering convenience and energy efficiency. Whether you're upgrading existing fixtures or designing new smart lighting setups, understanding these modules is crucial.
How to Find Reliable Infrared Receiver Module from China in 2025
China remains the global manufacturing hub for electronic components, including Infrared Receiver Modules. When sourcing from Chinese suppliers in 2025, consider these factors:
- Verify supplier certifications (ISO, RoHS)
- Request sample testing before bulk orders
- Check minimum order quantities and lead times
- Review trade assurance protections
Platforms like Alibaba showcase hundreds of verified manufacturers with competitive pricing (typically $0.50-$5 per unit depending on specifications).
What Buyers Should Know Before Buying Infrared Receiver Module from China
Key considerations include:
- Compatibility with your existing systems (38kHz is most common)
- Operating voltage range (3V-5V DC standard)
- Receiver sensitivity (measured in meters)
- Package type (through-hole or surface mount)
Case Study: A UK-based smart home installer reduced callback rates by 40% after switching to premium modules with anti-interference shielding.
Types of Infrared Receiver Module
Three primary variants dominate the market:
- Standard IR Receivers - Basic 38kHz modules for simple remote controls
- High-Sensitivity Modules - Extended range up to 15 meters
- Smart IR Receivers - With built-in signal processing for noisy environments
Functions and features of Infrared Receiver Module
Modern modules offer:
- Low power consumption (<1mA standby)
- Wide operating temperature (-25°C to +85°C)
- Compact SMD packaging (as small as 3mm x 3mm)
- EMI/RFI noise immunity
Advanced models now incorporate automatic gain control for consistent performance across varying distances.
Scenarios of Infrared Receiver Module
Beyond basic lighting control, these modules enable:
- Smart home automation integration
- Mood lighting scene selection
- Energy-saving occupancy detection
- Security system triggering
Commercial applications include hotel room lighting control and retail display management.
How to Choose Infrared Receiver Module
Selection criteria should include:
| Factor | Consideration |
|---|---|
| Range | 5m sufficient for most homes |
| Angle | ±45° typical, wider for large rooms |
| Protocol | NEC, RC5, or custom coding |
Pro Tip: For outdoor applications, look for weather-resistant models with IP65 rating.
Infrared Receiver Module Q & A
Q: Can IR modules work through walls?
A: No, infrared requires line-of-sight operation unlike radio frequency devices.
Q: What's the typical lifespan?
A: Quality modules last 50,000+ hours under normal conditions.
Q: How to troubleshoot non-responsive modules?
A: First check power supply, then test with known-good remote.
Q: Are universal remotes compatible?
A: Yes, if programmed to match the module's carrier frequency.
Q: Can sunlight interfere with operation?
A: Modern modules have sunlight filters, but direct exposure may cause issues.
