It utilizes an infrared emitting diode alongside a photodiode receiver to detect the presence and distance of reflective obstacles in front of it. When the emitted infrared light hits an object, it bounces back into the receiver, triggering a digital output response.\u003c\/p\u003e\n\n\u003cp\u003eAvailable now at Tomson Electronics, this specific board features an onboard LM393 voltage comparator and a highly useful built-in potentiometer (preset). This preset allows you to manually tune the sensor's detection threshold, effectively adjusting its sensitivity and sensing range to suit your specific project environment. With a wide operating voltage of 3.3V to 5V, it interfaces seamlessly with 3.3V microcontrollers like the ESP32 and STM32, as well as standard 5V logic boards like the Arduino Uno.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003ePeople also search for:\u003c\/strong\u003e infrared obstacle sensor, ir proximity module, lm393 ir sensor, line follower sensor, arduino distance sensor, adjustable ir sensor.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensor Type:\u003c\/strong\u003e Infrared Emitter \/ Receiver Pair\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComparator Chip:\u003c\/strong\u003e LM393 (Provides stable digital output)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Voltage (VCC):\u003c\/strong\u003e 3.3V to 5V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDetection Range:\u003c\/strong\u003e Approximately 2cm to 30cm (Adjustable via onboard preset)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Type:\u003c\/strong\u003e Digital (Outputs LOW when an obstacle is detected, HIGH when clear)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDetection Angle:\u003c\/strong\u003e ~35 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndicators:\u003c\/strong\u003e Onboard Power LED and Output Status LED\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eApplications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMobile Robotics:\u003c\/strong\u003e Serving as the primary \"eyes\" for obstacle-avoiding chassis or autonomous maze-solving robots.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLine Following:\u003c\/strong\u003e Detecting the contrast difference between black and white surfaces for line-follower bots.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustrial Prototyping:\u003c\/strong\u003e Building automated photoelectric counting systems for conveyor belts or assembly lines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecurity \u0026amp; Automation:\u003c\/strong\u003e Creating simple intrusion alarms or touchless automated hand sanitizer dispensers.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eFrequently Asked Questions (FAQ)\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I adjust the detection range?\u003c\/strong\u003e\u003cbr\u003e\nA: The board features a small blue potentiometer (the preset). Using a precision flathead screwdriver, slowly turn the dial while placing an object in front of the sensor. The onboard Output LED will light up when the threshold is crossed, allowing you to dial in the exact distance you need.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Will this sensor work perfectly outdoors in bright sunlight?\u003c\/strong\u003e\u003cbr\u003e\nA: IR sensors can struggle in direct sunlight because the sun emits a massive amount of infrared radiation, which can flood the photodiode receiver and cause false triggers. For outdoor robotics, ultrasonic or LiDAR sensors are generally recommended instead.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Can I measure exact distances (like 15.5 cm) with this board?\u003c\/strong\u003e\u003cbr\u003e\nA: No. Because this board relies on an LM393 comparator, it provides a \u003cem\u003eDigital\u003c\/em\u003e output (0 or 1). It only tells the microcontroller \"Yes, there is an object within range\" or \"No, the path is clear.\" If you need precise distance measurements, look into an Ultrasonic Sensor (HC-SR04) or a Time-of-Flight (ToF) sensor.\u003c\/p\u003e\n\n\u003ch5\u003ePackage Includes\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e1 × IR Proximity Sensor Board (with adjustable preset)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORTED","offers":[{"title":"Default Title","offer_id":48311812587758,"sku":"SEN-03140","price":39.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2132\/9029\/files\/IR_Proximity_Sensor_Module_with_Adjustable_Preset.jpg?v=1784027506","url":"https:\/\/www.tomsonelectronics.com\/products\/ir-proximity-sensor-module-infrared-obstacle-avoidance-for-arduino-by-adiy-copy","provider":"Tomson Electronics ","version":"1.0","type":"link"}
