When there is no obstruction in the module\nslot, the receiver tube will conduct and the module OUT will output a high\nlevel; When obstructed, OUT outputs a low level and the signal indicator light\ngoes out. The module OUT can be connected to a relay to form a limit switch\nand other functions, and can also be connected to an active buzzer module to\nform an alarm. The OUT output interface can be directly connected to the IO\nport of the microcontroller, usually connected to an external interrupt to\ndetect whether the sensor is blocked. If a motor encoder is used, the speed of\nthe motor can be detected. Precautions: Correct wiring! Do not reverse the\npositive and negative connections to burn out the electronic components of the\nboard. Players should set the I\/O port of the MCU to input mode\/receive mode,\notherwise it cannot be used. Other MCUs, or more advanced control boards such\nas ARM, must be set to input\/output mode if the I\/O port needs to be set to\ninput\/receive mode, otherwise it cannot be used. The 51 series microcontroller\ncan be used directly without the need to set input and output modes.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eAdopting a slot type photoelectric sensor, it consists of an infrared light-emitting diode and an NPN photoelectric transistor, with a slot width of 5.9mm.\u003c\/li\u003e\n         \u003cli\u003eAs long as a non-transparent object passes through the slot, it can trigger to output a low TTL level.\u003c\/li\u003e\n         \u003cli\u003eUsing Schmidt trigger to jitter pulses is very stable and can be used for small car speed measurement, distance measurement, and other applications!\u003c\/li\u003e\n         \u003cli\u003eInstall holes with M3 screws at both ends.\u003c\/li\u003e\n         \u003cli\u003eWorking voltage: 3.3V-5V, output form: digital switch output (0 and 1)\u003c\/li\u003e\n  \u003c\/ul\u003e","brand":"EC Buying","offers":[{"title":"Default Title","offer_id":43713323991220,"sku":"B0CHDRF497","price":107.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/9906\/1172\/files\/B0CHDRF497.jpg?v=1731570205","url":"https:\/\/auspowers.com\/products\/10pcs-ir-infrared-sensor-module-slotted-optical-optocoupler-speed-measuring-sensor-module-photo-interrupter-sensor-motor-speed-detection-robot-for-arduino","provider":"AusPower Australia","version":"1.0","type":"link"}
