It is specifically tuned to be most sensitive to wavelengths between 760nm and 1100nm, which is the primary spectrum for fire radiation. When IR light from a flame hits the black epoxy bulb of the sensor, it allows current to flow, which the module converts into a measurable signal.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e\u003cstrong\u003e\u003cbr\u003eWhy it’s a Robotics and Safety Essential:\u003c\/strong\u003e\u003cspan\u003e\u003cbr\u003e• Directional Detection: With a detection angle of approximately 60°, this sensor is excellent for pinpointing where a fire is located. By using three KY-026 sensors in a \"fan\" array, a robot can navigate toward or away from a fire with high precision.\u003cbr\u003e• Dual Output Utility:\u003cbr\u003eo Analog (A0): Provides a voltage that increases as the flame gets closer or larger. This is perfect for determining the \"intensity\" of the fire.\u003cbr\u003eo Digital (D0): Acts as a high-speed trigger. The onboard LM393 comparator flips the output to LOW the moment a flame is detected, which can trigger an immediate interrupt on your Arduino.\u003cbr\u003e• Adjustable Sensitivity: The onboard potentiometer allows you to tune out \"background noise\" (like sunlight or incandescent bulbs) so the sensor only reacts to an actual fire source.\u003cbr\u003e• Instant Response: Because it uses light rather than heat or chemicals, the response time is nearly instantaneous.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003cstrong\u003eTechnical Capabilities:\u003c\/strong\u003e\u003cspan\u003e\u003cbr\u003e• Operating Voltage: 3.3V to 5V (making it compatible with both Arduino and ESP32).\u003cbr\u003e• Detection Range: Can detect a standard flame from roughly 20cm to 100cm depending on the size of the fire and the sensitivity setting.\u003cbr\u003e• Signal LEDs: Includes a \"Power\" LED and a \"Signal\" LED that lights up the moment the digital threshold is crossed, making it easy to calibrate without looking at a serial monitor.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003cstrong\u003eBest For:\u003c\/strong\u003e\u003cspan\u003e\u003cbr\u003eThe KY-026 is the primary choice for firefighting robots, industrial furnace monitors, domestic fire alarms, and flame-activated security systems.\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"TinkEdge","offers":[{"title":"Default Title","offer_id":46404513005767,"sku":"TE-FLASE-074","price":57.78,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/6620\/6407\/files\/FlameSensorModuleLM393_1.png?v=1776774632","url":"https:\/\/shop.tinkedge.tech\/products\/flame-sensor-module-lm393","provider":"TinkEdge","version":"1.0","type":"link"}
