- Designed for decoding remote control IR signals and interfacing with microcontrollers.
Product Details
Key Features
- The TSOP1738 module integrates a PIN diode, pre-amplifier and demodulator to convert a 38 kHz modulated IR signal into a digital output. :contentReference[oaicite:3]{index=3}
- Operating On ~5 V supply with low current consumption (~0.4-1 mA) and high immunity to ambient light. :contentReference[oaicite:4]{index=4}
- Output is active-low: when a valid IR burst is received the output pin drops (goes low). :contentReference[oaicite:5]{index=5}
Applications
Ideal for DIY electronics projects, home automation, remote control signal decoding (TV, audio, IR remotes) and interfacing with microcontrollers (Arduino, ESP8266/ESP32 etc.).
