1838B IR Receiving Head Remote control receiver

The 1838B IR Receiving Head is a 3-pin infrared remote control receiver that picks up 38 kHz IR signals and outputs a clean digital signal your microcontroller can decode. It is the type of receiver found in TVs, set-top boxes and Arduino kits, and it works directly with 3.3 V and 5 V boards such as Arduino and ESP32.

1838B IR Receiving Head Specifications

• Type: integrated IR receiver with built-in demodulator
• Carrier frequency: 38 kHz
• Supply voltage: 2.7–5.5 V
• Output: digital, active low (goes low while an IR burst is received)
• Pins: 3 (OUT, GND, VCC from left to right, facing the dome)
• Mounting: through-hole, fits breadboards

1838B IR Receiving Head Applications

• Receiving codes from TV and Arduino kit remotes
• Remote-controlled robots, lamps and relays
• Learning remote controls and code cloning
• Media and home automation projects
• Electronics classes and STEM kits

What's in the Box

• 1 × 1838B IR receiver

Tip: Connect OUT to a digital pin and use the IRremote library to read the button codes. Double-check the pin order before powering up, since a reversed supply can damage the receiver, and add a 100 nF capacitor between VCC and GND if the readings are noisy.

Orders placed before 14:00 are ready for pickup the same day. Delivery across Lebanon usually takes 1–3 working days.
