LamaPLC: D6T Omron Non-Contact Thermal Sensors with I²C communication

The Omron D6T series consists of highly sensitive MEMS thermal sensors that measure surface temperature non-contact via infrared detection. Unlike conventional motion sensors, they can detect stationary humans based on their body heat, making them suitable for energy conservation and security applications.

• Non-Contact Measurement: Uses thermopile elements to absorb radiant energy from objects and convert it into a temperature reading.
• Presence Detection: A key strength is the ability to detect both moving and stationary humans and objects, unlike typical pyroelectric sensors that rely solely on motion.
• High Signal-to-Noise Ratio (SNR): Omron's unique MEMS and ASIC technology delivers a high SNR, ensuring stable, accurate temperature measurements.
• Digital Output: Provides a direct digital temperature value via an I²C interface, simplifying software design and enhancing noise immunity.
• Compact Size: The sensors integrate all components (silicon lens, thermopile, ASIC) into a compact, space-saving package suitable for embedded applications.
• Various Array Options: Available in different configurations, including single-element (1×1), strip (1×8), and array (4×4, 32×32) formats, to suit various field-of-view (FoV) requirements.
