PRESTONICs Ltd. presents the DK-GS-001 Gas Sensor manufactured by DK Sensor, a state-of-the-art, MEMS-type multi-pixel module engineered for highly responsive tracking of TVOC, HCHO, and NO₂ concentrations. Fully optimized for professional “Design-in” engineering and high-volume OEM appliance integration, this miniature module delivers the precise digital interface and Project Protection demanded by advanced climate and environmental control architectures.
The sensor is strategically configured with a high-performance chemical sensing die to deliver precise and actionable air quality data:
High-Sensitivity Resistance Evaluation: Monitors air quality by precisely measuring the decrease in electrical resistance as target gas concentrations increase, ensuring rapid data updates.
Multi-Pixel Sensing Matrix: Configured with a dedicated multi-pixel matrix optimized to detect and quantify concentration ranges for Ethanol/TVOC (300 to 10,000 ppb) and Nitrogen Dioxide (NO₂: 50 to 650 ppb).
Digital I2C Communication: Integrates a native digital 2-wire I2C interface, enabling direct, high-fidelity data communication with master microcontrollers without needing external analog signal conditioning.
Ultra-Low Power Profiling: Features a highly optimized power footprint drawing a low operating supply current and a typical idle current of just 34µA, making it ideal for energy-conscious smart systems.
Internal Heating Functionality: Equipped with an integrated internal heating element that maintains stable chemical reaction thresholds across a wide operating temperature range of -20°C to +55°C.
