Feature

Wide Voltage Supply Compatibility: The sensor supports a wide voltage range and can be powered directly by the PWM signal line of a drive fan, providing flexibility in various applications.
Compact and Flexible Design: Utilizes an emission and reception separation structure, resulting in a compact size. This makes the sensor suitable for installation in complex and constrained environments.
High Measurement Precision: Capable of detecting minimum particle sizes as small as 10μm at wind speeds of 12 m/s, ensuring accurate monitoring even in challenging conditions.
Fast Response Time: With a response time of less than 0.3 seconds, the sensor provides real-time monitoring for immediate feedback.
Wide Measurement Range: Supports two options for dust concentration measurement: 0-999 mg/m² and 0-9999 mg/m², making it adaptable for various detection needs.
Low Power Consumption: Features energy-efficient operation with an active current of less than 30mA and standby current below 0.5mA, ideal for long-term use in battery-powered systems.
Versatile Application Scenarios: Suitable for integration into vacuum cleaners, robotic sweepers, air purifiers, and other intelligent detection devices, offering a broad range of usage scenarios.

Tips: What makes the sensor suitable for use in vacuum cleaners or sweepers?

The optical dust sensor’s fast response time (≤0.3 seconds) and high sensitivity to dust particles make it ideal for real-time monitoring in vacuum cleaners, robotic sweepers, and other cleaning devices. It helps these machines adjust their suction power based on the dust concentration, improving cleaning efficiency and optimizing energy usage. Its compact size and low power consumption further ensure seamless integration into portable devices.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
