It's the advanced version of the SEN0381, offering a longer sensing range and an onboard status indicator LED.\n\nDetection distance is adjustable — hold the onboard button for 3 seconds, then set your desired range. The sensor automatically saves the configured distance. Digital signal output makes it easy to integrate with Arduino and DFRobot IO Expansion Shields.\n\nKey Features\n\n\nAdjustable Range – Set detection distance from 1 to 400 cm via onboard button\n\nLaser Sensing – 940 nm laser with diffuse reflection detection\n\nIP67 Waterproof – Suitable for outdoor and harsh environments\n\nDigital Output – High/low level signal, compatible with Arduino\n\nShort Circuit Protection – Automatically disables output above 1 A\n\nWide Voltage Range – 5–24 V DC power supply\n\n\nSpecifications\n\n\nPower Supply – DC 5–24 V\n\nOperating Current – 15 mA\n\nLoad Current – 300 mA\n\nDetection Distance – Adjustable, 1–400 cm\n\nDetection Accuracy – ±4%\n\nWavelength – 940 nm laser emitter\n\nDetection Angle – 35° (transmit), 25° (receive)\n\nOperating Temperature – −20 to 70 °C\n\nStorage Temperature – −20 to 85 °C\n\nWaterproof Rating – IP67\n\nMaterial – PC optical filter, PC-V0 fireproof housing\n\n\nIdeal For\n\nRobot obstacle avoidance\nSmart home automation\nSecurity and intrusion detection\nProximity-triggered control systems\n\n\nPackage Contents\n\n1× Digital Laser Proximity Sensor (1–400 cm)\n\n\nResources\n\nProduct Wiki\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2238,"title":"Default Title","sku":"DF-SEN0531","price":41.21,"on_sale":false,"in_stock":true,"available_quantity":130,"option1":"Default Title"}]}
