Using FMCW modulation, it measures distance to object surfaces by transmitting and receiving microwaves, with all signal processing integrated on-board. Distance data is output directly via an asynchronous serial interface (ASI) at 3.3V TTL logic level.\n\nCompared with optical and ultrasonic range sensors, this microwave radar offers a wider detection range and reliable performance in harsh conditions — it can penetrate most non-metallic materials, dust, smoke, and fog. The sensor also supports multi-target distance detection and custom working modes for processing distance spectral information.\n\nKey Features\n\n\n24GHz FMCW Radar – Millimetre-wave ranging with 0.5–20m detection distance\n\nHigh Resolution – 0.01m range resolution with ±0.1m accuracy\n\nMulti-Target Detection – Detect distances to multiple objects simultaneously\n\nAll-Weather Operation – Penetrates dust, smoke, fog, and non-metallic materials\n\nSerial Interface – ASI communication at 57,600 bps, 3.3V TTL logic\n\nCompact & Lightweight – Just 34 × 44 × 5mm and 8g\n\n10Hz Update Rate – Fast, responsive distance measurements\n\n\nSpecifications\n\n\nInput Voltage: 4–8V DC\n\nLogic Level: 3.3V TTL\n\nInput Current: >100mA\n\nPower Consumption: 400mW\n\nTransmit Power: 0–10dBm\n\nModulation: FMCW\n\nDetection Distance: 0.5–20m\n\nRange Resolution: 0.01m\n\nAccuracy: ±0.1m\n\nH-Plane Beamwidth: 78° (-3dB)\n\nV-Plane Beamwidth: 23° (-3dB)\n\nData Update Speed: 10Hz\n\nWorking Temperature: 0–70°C\n\nStorage Temperature: -40–85°C\n\nDimensions: 34 × 44 × 5mm\n\nWeight: 8g\n\n\nIdeal For\n\nCar reverse backup radar systems\nAutomatic door openers\nUAV obstacle avoidance\nPassenger flow detection\nCollision prevention devices\n\n\nPackage Contents\n\n1× 24GHz Microwave Radar Sensor (SEN0306)\n\n\nResources\n\nDFRobot Product Wiki\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4856,"title":"Default Title","sku":"DF-SEN0306","price":128.11,"on_sale":false,"in_stock":true,"available_quantity":53,"option1":"Default Title"}]}
