It uses an IR emitter and position-sensitive detector to measure distance, making it unaffected by the colour or reflectivity of most objects.\n\nThe sensor terminates in a 3-pin JST connector. Use a JST pigtail cable for easy connection, or solder wires directly to the back of the module.\n\nSpecifications\n\n\nPart Number: GP2Y0A21YK\n\nDetection Range: 10–80 cm\n\nOutput: Analogue voltage (0.4–3.1 V)\n\nSupply Voltage: 4.5–5.5 V\n\nConnector: 3-pin JST\n\nManufacturer: Sharp\n\n\nIdeal For\n\nObstacle avoidance on robots\nDistance measurement projects\nObject detection and proximity sensing\nArduino and microcontroller projects\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":11174,"title":"Default Title","sku":"SF-SEN-00242","price":30.45,"on_sale":false,"in_stock":true,"available_quantity":143,"option1":"Default Title"}]}
