The TSOP1838 (JS-1838B) Infrared Remote Receiver is a 3-pin IR demodulator module designed to detect and decode signals from standard 38kHz infrared remote controls. It combines a PIN photodiode and preamplifier in a single TO-92 package for reliable remote-control sensing.
Key features:
- 38kHz Carrier Detection: Tuned to demodulate the 38kHz carrier frequency used by most consumer IR remotes.
- Digital Output: Delivers an active-low logic-level output that can be read directly by a microcontroller pin.
- Long Reception Range: Detects signals from several meters away under normal ambient light.
- Built-In Noise Filtering: Internal circuitry rejects ambient light and electrical noise for cleaner decoding.
- Simple 3-Pin Wiring: OUT, GND, and VCC pins connect directly to Arduino, ESP32, or other microcontroller boards.
- Low Power Consumption: Draws minimal current, suitable for battery-powered remote-control receivers.
It’s a go-to component for building universal remotes, IR-controlled robots, and home automation projects that need to recognize standard remote-control signals.
