PRESTONICs Ltd. presents the DK-DS-001 Dust Sensor manufactured by DK Sensor, a highly sensitive optoelectronic module engineered for accurate real-time evaluation of airborne dust and fine particulates in domestic and commercial environments. Fully optimized for professional “Design-in” engineering and high-volume OEM appliance integration, this compact sensor delivers the stable calibration and Project Protection required for modern, responsive air quality applications.
The sensor is strategically configured with a high-performance optical sensing chamber to deliver precise and actionable air quality data:
Dual-Channel Fine Dust Tracking: Features two independent digital outputs (P1 and P2), allowing simultaneous monitoring of standard dust particles (1.0µm and larger) and ultra-fine particulates down to 0.7µm.
Integrated Self-Airflow Generation: Engineered with an internal heating element that creates an autonomous thermal draft, drawing outside air through the sensor without requiring secondary mechanical aeration.
Space-Efficient Profile: Built on a highly compact footprint measuring just 59mm x 45mm, allowing for easy mechanical handling and effortless integration into tight, low-profile product enclosures.
Digital Negative-Logic Interfacing: Outputs clear, low-time-ratio digital signals compatible with standard microcontrollers, optimized for a recommended unit sampling time of 30 seconds.
Technical Specifications Summary:
Operating Voltage: DC 5V ± 10% (Low ripple ≤ 30mV)
Current & Power Consumption: 90mA operating current; max 0.15W signal / 0.8W heater
Environmental Thresholds: 0°C to 45°C operating range; up to 95% RH (non-condensing)
Concentration Range: P1 up to 8,000 pcs / 283ml; P2 up to 4,000 pcs / 283ml
Designed for exceptional environmental resilience, the DK-DS-001 is the ideal choice for high-efficiency air cleaners, smart automated ventilators, household air conditioners, and dedicated indoor air monitoring systems.
