Abstract The increasing demand for low‐power, compact, and efficient gas sensors next‐generation technologies like Internet of things (IoT) platforms portable devices drives the advancements in self‐powered sensing systems. Photovoltaic have emerged as a promising solution, harvesting light energy without external power. However, existing designs are limited by complex fabrication processes focus on oxidizing gases, which leaves behind reducing particularly volatile organic compounds (VOCs). This study presents transparent, solution‐processed ZnO/CuI heterojunction‐based UV light‐induced photovoltaic (UV‐PSP) sensor selective detection VOC n‐butylamine. exhibits good sensitivity (0.0709), limit (6.6 ppm), response (10% at 25 ppm). heterojunction provides high electron mobility, chemical stability, hydrophobicity, ensuring robust real‐time monitoring. also demonstrates long‐term stability (>80% retention over days) reduced humidity interference. mechanism is investigated via Scanning Kelvin Probe to reveal charge transfer dynamics. A functional IoT‐enabled prototype further validates its practical applicability environmental industrial applications, offering continuous remote establishes versatile energy‐efficient platform sustainable
