the junction for ambient IR. For remote decoding, a simple op‑amp comparator or a pull‑up resistor to a digital pin works. Reverse bias the BPW34 for improved speed and shield it from ambient light to reduce noise.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"faq\"\u003e\n  \u003cdiv class=\"faq-item\"\u003e\n    \u003ch3\u003eWhat voltage does BPW34 output?\u003c\/h3\u003e\n    \u003cp\u003eIt delivers a photocurrent proportional to IR intensity; you need a load resistor to convert it to a voltage, typically 0–5V with a 10kΩ resistor.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"faq-item\"\u003e\n    \u003ch3\u003eCan BPW34 replace an IR receiver module like TSOP1738?\u003c\/h3\u003e\n    \u003cp\u003eNo, the BPW34 is a raw photodiode without demodulation.
