It is driven by an XMC1302 MCU based on Arm® Cortex®-M0. This comes in a compact package and runs on very low power, providing high-precision measurements of objects' movement and speed.\n\u003c\/p\u003e\n\u003ch2\u003e\n Features\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  The first radar-based sensor in the Grove Family\n \u003c\/li\u003e\n \u003cli\u003e\n  Compact size for easy deployment\n \u003c\/li\u003e\n \u003cli\u003e\n  Light-weight design, suitable for UAV applications\n \u003c\/li\u003e\n \u003cli\u003e\n  Low power consumption for prolonged usage\n \u003c\/li\u003e\n \u003cli\u003e\n  24GHz Transceiver MMIC for high-precision measurements of movement and speed\n \u003c\/li\u003e\n \u003cli\u003e\n  Fast response using electromagnetic waves\n \u003c\/li\u003e\n \u003cli\u003e\n  ESD protection to avoid system failures caused by ESD strikes\n \u003c\/li\u003e\n \u003cli\u003e\n  High penetration which allows it to be deployed behind an object\n \u003c\/li\u003e\n \u003cli\u003e\n  Maintains operation through harsh weather conditions (temperature, light, dust, rain)\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n How Does Doppler Radar Technology Work?\n\u003c\/h2\u003e\n\u003cp\u003e\n Doppler radar works by sending a beam of electromagnetic radiation waves from the transmitter (TX Antenna), with a precise frequency, at a moving object.\n\u003c\/p\u003e\n\u003cp\u003e\n Once the electromagnetic radiation wave comes in contact with an object, it travels back towards the receiver (RX Antenna). However, when the wave got reflected from the moving object, the wave now has a different frequency compared to the original frequency, it emitted.\n\u003c\/p\u003e\n\u003cp\u003e\n \u003cimg alt=\"\" class=\"aligncenter size-full wp-image-510447\" height=\"1531\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0914\/9972\/5181\/files\/DIAGRAM-1_6bd03cf7-90b5-4dc3-a18b-0ac9f298575b.png?v=1754233840\" width=\"1920\"\u003e\n\u003c\/p\u003e\n\u003cp\u003e\n Then the change in this frequency can be used to calculate the velocity of the moving object.
