Sensor radar uRAD Doppler v1.0 de 24 GHz

01 The sensor

Measure speed, direction and motion with 24 GHz Doppler radar.

uRAD Doppler emits a 24 GHz continuous wave (CW) and analyzes its echo to determine target speed and direction in real time — with no cameras, no contact and no moving parts.

It integrates antennas and signal processing on a high-frequency substrate in an 8 grams, ready to connect via UART from day one.

04 Capabilities

Accuracy and direction in every reading.

Four capabilities that define what you can build with uRAD Doppler.

Industrial-grade accuracy

Measure from 8 km/h to 322 km/h with ±0.18 m/s (0.66 km/h) accuracy. Ideal for technical validation, speed monitoring and sports measurement.

Knows whether a target is approaching or moving away

Returns direction and speed in every frame, without extra sensors or external processing to determine movement direction.

Trigger external systems

Two threshold-configurable GPIO outputs can activate signs, alarms or panels when a target exceeds a set speed.

Advanced RAW I/Q data

Extract In-phase and Quadrature signals through the serial port for vibration analysis, micro-displacements or custom signal processing.

05 Applications

Applications for the Doppler radar sensor.

uRAD Doppler is primarily designed for non-contact speed and direction measurement. From that core capability, it can be integrated into technical applications where target motion is the key data point.

Vehicle speed monitoring

Build compact speed monitoring systems for urban and interurban roads. Measure up to 170 m with ±0.18 m/s accuracy, ideal for traffic monitoring and statistics.

170 m range322 km/h±0.18 m/s

Frequently asked questions about the Doppler radar sensor.

Is this a ready-to-use product or an integration module?

It is an integration module: a radar board that is ready to connect and evaluate, designed to be integrated into your own system. It includes documentation, a GUI, and an SDK, but it is not a complete radar system with an enclosure or display.

What do I need to connect it to a computer?

The uRAD Doppler module, a JST cable, a USB-UART adapter and a suitable power supply (3.5–6 V DC). With that, you can read data from the GUI on your PC.

Can I use it with Arduino, ESP32 or Raspberry Pi?

Yes. It communicates via 0–3.3 V UART, compatible with Raspberry Pi, ESP32 and microcontrollers with 3.3 V UART. For 5 V Arduino boards, use a logic-level converter.

Can I integrate it into my system?

Yes. It communicates via 0–3.3 V UART with a documented serial protocol and includes a Python SDK, so you can connect it to a PC via UART/USB adapter, microcontrollers or embedded systems.

Do I need programming skills?

For basic tests, no: the included graphical interface (GUI) lets you operate the sensor and export data without programming. For advanced integration, you can use the Python SDK and UART data.

What exactly does it measure?

Speed and motion without contact using 24 GHz continuous-wave (CW) Doppler radar. It provides the speed of approaching and moving-away targets, and detects presence and movement direction.

What is the range and accuracy?

It measures from 8 km/h to 322 km/h (±2 m/s to ±90 m/s) with ±0.18 m/s (0.66 km/h) accuracy. Range reaches up to 170 m for vehicles, depending on installation.

Can it be used for speed feedback signs?

Yes. With up to 170 m range and two threshold-configurable GPIO outputs, it can directly trigger lights or speed feedback signs when a given speed is exceeded.

Can I use RAW I/Q data?

Yes. RAW DATA mode lets you extract In-phase (I) and Quadrature (Q) components through the serial port, ideal for advanced signal processing, vibration analysis or micro-displacement measurement.

What power supply does it need?

It operates from 3.5 to 6 V DC (5 V DC recommended), with 137 mA / 0.7 W consumption. Connection is made through the 7-pin JST B7B-XH-A connector.
