DAI640Pro Uncooled Infrared Thermal Imaging Module: Ultra-Compact Low-Power Core for Drone Payloads & OEM Integration

Every gram matters in drone payload design, and the DAI640Pro uncooled infrared thermal imaging module sets a new standard with its 20×20×14 mm PCB and 9.1 g mass. Its typical power consumption stays well below 1 W, directly translating to extended flight times—a critical advantage for prolonged search‑and‑rescue or agricultural inspection missions. Additionally, the shutterless thermal module architecture not only reduces mechanical complexity but also guarantees start‑up in under 7 seconds, so the operator never misses critical heat signatures. Built‑in reverse polarity and under/over voltage protection safeguard the module across a wide 2.5 V to 5.5 V input range, allowing safe direct battery operation without complex regulation. Furthermore, flexible interfacing is provided by a BT.656 digital video output, RS‑232 communication, and analog PAL (CVBS) output, accommodating diverse system architectures. All these strengths make the DAI640Pro uncooled infrared thermal imaging module an excellent OEM thermal module for integrators who demand reliability and performance in the most constrained environments.

At the heart of the module lies an infrared microbolometer with 640×480 resolution and a fine 12 μm pixel pitch. This 640×480 detector captures fine thermal details, achieving a sensitivity of ≤40 mK (NETD) that reveals even subtle temperature differences. Meanwhile, the 8–14 μm long‑wave infrared band penetrates smoke, dust, and fog, ensuring reliable operation in adverse conditions. The shutterless design uses advanced Digital Detail Enhancement (DDE) to continuously compensate for non‑uniformities, producing a crisp 768×576 PAL‑format image at 25 Hz. The native 50 Hz frame rate preserves motion sharpness for fast‑moving drones. Users can select from multiple optional lenses—12 mm, 19 mm, 25 mm, 35 mm, and up to 50 mm—to tailor the field of view. Moreover, real‑time image adjustments such as black‑hot/white‑hot polarity, pseudo‑color palettes, and 1× to 8× digital zoom (0.1× steps) give operators total control over scene interpretation. Consequently, the DAI640Pro uncooled infrared thermal imaging module bridges high‑end performance and field‑practical flexibility, making it a go‑to choice for demanding thermal tasks.

The versatility of the DAI640Pro uncooled infrared thermal imaging module extends far beyond drone payloads. In security and surveillance, its 640×480 resolution supports covert monitoring and perimeter protection, while the shutterless operation guarantees silent, maintenance‑free use. For industrial predictive maintenance, the module’s superior thermal sensitivity spots overheating components in electrical cabinets and mechanical bearings before failures occur. Similarly, handheld diagnostic tools for building inspectors and firefighters benefit from its compact size and instant start‑up. Automotive night vision systems also gain enhanced situational awareness thanks to the high‑resolution infrared microbolometer. Additionally, when paired with an AI image processing board like the Trac‑DA053LE, the DAI640Pro enables onboard object detection and tracking—crucial for autonomous UAV missions. Its ruggedness, meeting GJB 150 vibration and shock standards, and an operating range from -40 °C to +60 °C (special grade) ensure dependability in extreme environments. This low power thermal module, weighing just 9.1 g, truly redefines what’s possible in portable thermal imaging. The DAI640Pro uncooled infrared thermal imaging module therefore represents a forward‑looking solution for any integrator aiming to maximize performance in minimal space and power budgets.
