Product description
Forget about ultrasonic and infrared sensors—the SparkFun Qwiic Pulsed Coherent Radar Sensor - Acconeer XM125 brings advanced 60 GHz radar technology to your projects. Unlike traditional sensors, this radar can detect objects through walls, cabinets, and even pockets, making it perfect for innovative applications. It offers millimeter-precision distance measurements, motion detection, speed tracking, and even gesture recognition.
With a range of up to 20 meters, the XM125 is ideal for long-range sensing tasks. The actual detection range depends on factors like object size, shape, material, and lens usage (e.g., water level detection up to 20 meters with a lens, human presence detection up to 7 meters without one). Despite its capabilities, it consumes very little power, making it suitable for battery-powered projects. The sensor can also distinguish between stationary objects and moving targets using pulsed coherent radar, letting you detect both the presence and speed of objects.
The XM125 features a USB Type-C connector, ESD protection, and a CH340C USB-to-serial converter for easy computer connection. It includes voltage regulators and buttons for reset and boot mode. Thanks to the Qwiic system, no soldering is needed to integrate it into your setup, though breadboard-friendly pins are also available.
We’ve developed an Arduino library for the XM125 when loaded with I2C presence or distance detection firmware. This allows you to detect object movement and measure distances with adjustable sensitivity and range. You can also fine-tune the sensor’s settings using Acconeer’s Python-based Exploration Tool, which provides real-time data visualization and supports Windows and Linux.
The SparkFun Qwiic Pulsed Coherent Radar Sensor opens up exciting new possibilities for projects like smart home presence detection, security systems, parking space monitoring, gesture controls, level measurements, through-wall imaging for search and rescue, and advanced robotics.
Note: Due to its high frequencies, the use of pulsed coherent radar sensors may be regulated in some countries, so be sure to check local regulations.
