LD2413 24GHz Millimeter-Wave Level Sensor | High-Precision Distance Measurement ±3mm | 0.15-10m Range | FMCW Radar | 3.3V UART

The LD2413 is a compact 24GHz millimeter-wave sensor designed for non-contact level and distance measurement. Thanks to modern FMCW radar technology and integrated intelligent signal-processing algorithms, the sensor reliably measures liquids and bulk materials in open or closed containers – even under demanding environmental conditions.

Main Features at a Glance

• Precise distance measurement: Measurement range approx. 0.15m to 10m, ideal for typical level measurement applications in tanks, containers, and shafts.
• High accuracy: Typical measurement error in the millimeter range – perfect for applications requiring high precision.
• 24GHz FMCW radar technology: Reliable detection even in dusty, steamy, or varying temperature environments.
• Non-contact & wear-free: no contact with the medium, no corrosion, and no mechanical wear.
• Compact design: only approx. 44mm × 36mm – ideal for integration into custom devices and enclosures.
• Energy-efficient: very low average current consumption for typical reporting cycles, suitable for continuous or battery-powered operation.
• UART interface: easy connection to microcontrollers, embedded systems, or IoT gateways (115200 baud).
• Configurable parameters: including min/max detection distance and reporting interval via serial protocol.

Typical Applications

• Level monitoring in tanks, containers, and silos
• Water level measurement in shafts, wells, or open basins
• Integration into smart household appliances (e.g., water dispensers, coffee machines)
• Industrial process monitoring and automation
• Hydrological measurements in channels, rivers, or catch basins
• Smart-city and infrastructure monitoring (rainwater, drainage systems, etc.)

Technical Data

Integration Notes

• The sensor is typically mounted on the top of tanks or containers, with the antenna surface perpendicular to the medium's surface.
• Avoid metallic parts or strong reflectors in the sensor's direct field of view to minimize interference.
• Parameter configuration (e.g., min/max distance, reporting interval) is performed via the serial protocol and can be adjusted as needed for the application.
