DIY Millimeter-Wave Sensor Exploration Combo – A Multi-Sensor Hybrid Kit

We are often asked: Which millimeter-wave sensor is the best?

That’s a tough question—each type has its own strengths.

Some sensors support XY coordinate detection for defining zones; in our experiments, a few can even detect XYZ coordinates. However, those sensors may have weaker static detection capabilities.

On the other hand, some sensors offer excellent static detection with a wide range, but they don’t support XY coordinate output.

To help newcomers get started with millimeter-wave technology, we’ve curated a few DIY combo options that offer a great starting point—plus, we’re offering a 20% DIY discount:

Combo 1: 2A + L13

Includes the LD2450 and LD2412S.

- LD2450 supports zone detection (with weaker static detection).

- LD2412S provides powerful static detection over a large range (but without XY coordinate output).

Combo 2: 2A + 1MS + L13

Includes LD2450, LD2412S, and LD2410.

- LD2410 is one of the most well-known HLK millimeter-wave sensors—less powerful than the LD2412S in static detection and range, but a time-tested classic trusted by countless hobbyists.

Combo 3: 2A + 1MS + L13 + F2

Includes LD2450, LD2412S, LD2410, and LD1125F.

- LD1125F is a long-range mmWave sensor: It’s simple and highly reliable—no BLE or advanced features, just three basic parameter settings (no gate adjustment). It’s also energy-efficient and runs cool.

This kit is ideal for anyone curious about the real-world differences between these sensors.
