{"title":"5.8GHz Microwave Radar Module","handle":"5-8ghz-microwave-radar-module","url":"/products/5-8ghz-microwave-radar-module","description":"The 5.8GHz Microwave Radar Module is a high-sensitivity motion detection sensor that transmits and receives 5.8GHz electromagnetic waves. By analysing the difference between transmitted and reflected signals, it reliably detects movement within its detection zone.\n\nUnlike traditional PIR sensors that only respond to large body movements, this FMCW/CW microwave radar can detect subtle motion such as breathing, making it capable of true human presence detection — even when a person is sitting still or sleeping. Results are output via UART serial or digital I/O level.\n\nKey Features\n\n\nHuman Presence Detection – Detects micro-movements like breathing, not just walking\n\nDual Modulation – Supports both FMCW and CW radar modes\n\nWide Beam Angle – 120° × 120° detection cone covers large areas\n\nLong Range – Up to 11m detection distance\n\nDual Output – UART serial (115200 baud) and digital I/O level output\n\nCompact Design – Just 20 × 18mm, easy to integrate into enclosures and projects\n\nWide Temperature Range – Operates from −40°C to +85°C\n\n\nSpecifications\n\n\nOperating Frequency: 5.8GHz\n\nModulation Mode: FMCW, CW\n\nOperating Voltage: 4.5–5.5V\n\nOperating Current: 22mA\n\nDetection Distance: 11m\n\nEquivalent Transmission Power: 3–5dBm\n\nBeam Angle: 120° × 120°\n\nBaud Rate: 115200\n\nOperating Temperature: −40°C to +85°C\n\nDimensions: 20 × 18mm\n\n\nIdeal For\n\nSmart lighting and occupancy-based automation\nSecurity and intrusion detection systems\nHome appliance presence sensing\nHotel and building room occupancy monitoring\nGarage and parking detection\n\n\nPackage Contents\n\n1× 5.8GHz Microwave Radar Module\n\n\nResources\n\nProduct Wiki & Documentation\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2104,"title":"Default Title","sku":"DF-SEN0521","price":21.37,"on_sale":false,"in_stock":true,"available_quantity":94,"option1":"Default Title"}]}
