HLK-LD2413 24G Water Level Detection Sensor Radar Module Liquid Detection Non-Contact Sensor Switch
The HLK-LD2413 is a compact, high-precision 24GHz radar-based water level and material level detection sensor developed by Hi-Link. It combines an advanced millimeter wave radar module with intelligent firmware to provide reliable, contactless measurement in real time.
This HLK-LD2413 24G Wasserstandserkennungssensor features a powerful AIoT-enabled radar SoC, a high-performance microstrip antenna (1T1R), and integrated signal processing firmware using FMCW waveform for accurate level detection.
With a measurement range of 0.15 to 10 meters and ±3mm accuracy, it performs consistently in demanding environments, including dusty, pressurized, or sealed containers—making it a top choice for industrial, smart city, and home appliance applications.

Precautions
- Ensure the sensor's antenna is directly facing the detection area, and the surrounding space is open and unobstructed.
- The installation position of the sensor must be secure and stable, as sensor movement will affect detection accuracy.
- Ensure there are no moving objects or vibrations behind the sensor. Since radar waves can penetrate objects, the rear lobe of the antenna may detect movement behind the sensor. To mitigate this, use a metal shield or metal backing to block the rear lobe and reduce the impact of objects behind the sensor.
- If there are multiple 24 GHz radars in the working environment, avoid having their beams face each other, and install them at a distance to minimize potential interference.
- The power input voltage range is 3.0V~3.6V, with no significant spectral peaks in the power ripple within 2MHz. This solution is provided as a reference, and users should consider appropriate electromagnetic compatibility designs, such as ESD protection and lightning surge protection.
