{"title":"Digital IR Proximity Sensor (0-200cm)","handle":"digital-ir-proximity-sensor-0-200cm","url":"/products/digital-ir-proximity-sensor-0-200cm","description":"A digital infrared proximity sensor with an adjustable detection range of 0–200 cm. It uses diffuse IR reflection to detect objects or people, outputting a digital high signal when something enters the sensing zone and returning to low when cleared — ideal for smart home, security, robotics, and automation applications.\n\nDetection distance is easily configured using the onboard button: press and hold while the indicator flashes, then position the target at your desired distance. The sensor automatically saves the calibration. A standard 3-pin digital cable connects directly to Arduino I/O expansion boards.\n\nKey Features\n\n\nAdjustable Detection Range – 0–200 cm, set via onboard button\n\nDigital Output – Active-high switch signal\n\nIP67 Waterproof – Suitable for outdoor and harsh environments\n\nWide Detection Angle – 30–40° cone\n\n3-Pin Interface – Plug directly into Arduino expansion boards\n\n\nSpecifications\n\n\nPower Supply: 5 V\n\nDetection Distance: 0–200 cm (adjustable)\n\nOutput: Digital switch (active-high)\n\nDetection Angle: 30–40° cone\n\nOperating Temperature: −10 to 60 °C\n\nStorage Temperature: −20 to 70 °C\n\nWaterproof Rating: IP67\n\n\nIdeal For\n\nSmart home and security systems\nRobot obstacle detection\nAutomated door and gate triggers\nIndustrial presence sensing\n\n\nResources\n\nProduct wiki\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3671,"title":"Default Title","sku":"DF-SEN0381","price":21.83,"on_sale":false,"in_stock":true,"available_quantity":516,"option1":"Default Title"}]}
