Key Features:

✔ 38kHz Modulated IR Detection – Compatible with 99% of consumer remotes. ✔ Strong Noise Immunity – Built-in AGC (Automatic Gain Control) to reject interference. ✔ Digital Output (Active-Low) – Outputs LOW when IR signal is detected, else HIGH. ✔ Wide Voltage Range (2.5V–5.5V) – Works with 3.3V and 5V logic devices. ✔ Low Power Consumption – Only 0.5mA standby current (ideal for battery projects). ✔ Compact 3-Pin Design – Easy breadboard or PCB integration.

Applications:

• Smart Home Automation – Control lights, fans, and appliances via remote.

• DIY Remote Systems – Custom IR controllers for robots/drones.

• TV-Box Hacking – Add IR to Raspberry Pi media centers.

• Educational Electronics – Learn IR communication protocols.

Pinout & Wiring:

• OUT → Microcontroller input (e.g., Arduino pin 11).

• GND → Ground.

• VCC → 2.5V–5.5V power.

Technical Specifications:

• Carrier Frequency: 38kHz (±1kHz tolerance).

• Detection Range: Up to 45 feet (depends on remote strength).

• Field of View: ±45° (wide-angle reception).

• Response Time: <10ms (fast enough for most remotes).

• Dimensions: 18mm × 10mm × 7mm.

Package Includes:

• 1x TSOP1838B IR Receiver Module.

• Optional: Jumper wires (select if needed).

Why Choose the TSOP1838B?

✅ Plug-and-Play – Works with Arduino’s IRremote library. ✅ Reliable Decoding – Fewer false triggers than basic photodiodes. ✅ Globally Compatible – Supports NEC, Sony, RC5, and other IR protocols.
