Forget ultrasonic and infrared sensors; the SparkFun Qwiic Pulsed Coherent Radar Sensor - Acconeer XM125 brings powerful 60 GHz radar technology to your projects. This sensor isn't limited to surface detection; it can see through walls, cabinets, and even pockets (depending on the material), making it perfect for unique applications. Measure distances with millimeter precision, detect motion, the speed of an object, or even gestures! The XM125 boasts an impressive range of up to 20 meters, allowing you to create long-range sensing projects. The actual measurable distance is dependent on the object size, shape, dielectric properties, and lens (e.g. water level measurements up to 20 meters with lens utilization, human presence detection up to 7 meters with lens-free utilization). Despite its power, the sensor has remarkably low in power consumption, which is ideal for battery-powered applications. The real magic lies in the sensor's ability to do more than measure distance; the XM125 can differentiate between stationary objects and moving targets using pulsed coherent radar. This means you can sense an object's presence and how fast something is moving! We've included a USB type-C connector, ESD protection diodes on the USB data lines, and a CH340C USB-to-serial converter to connect the XM125 directly to your computer's COM port. Power is regulated down for the XM125 with the AP2112K 3.3V/600mA and RT9080 1.8V/600mA voltage regulators. Buttons for reset and boot are included when resetting the module or setting the board into bootloader mode. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1in.-spaced pins if you prefer a breadboard. With the SparkFun Qwiic Pulsed Coherent Radar Sensor, a world of new project possibilities opens up. Imagine creating presence detection systems for smart homes and security applications, parking space occupancy detection, gesture recognition interfaces for unique user control, level measurement (for example, in tanks or waste containers), through-wall imaging systems for search and rescue, or even advanced robotics with object avoidance and navigation. Note: Due to the higher frequencies, pulsed coherent radar sensors may be regulated in certain countries. Be sure to check local regulations before use. The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can't hook it up wrong.
