It provides digital and analog outputs, with sensitivity adjustable using the onboard potentiometer. It can be used with Arduino, Raspberry Pi, ESP32 and other microcontrollers.<\/p>\n<h4>Specifications<\/h4>\n<ul>\n<li><strong>Detection angle:<\/strong> 60\u00b0<\/li>\n<li><strong>Operating voltage:<\/strong> 3.3\u20135 V<\/li>\n<li><strong>Operating current:<\/strong> 15 mA<\/li>\n<li><strong>Outputs:<\/strong> digital HIGH\/LOW and analog<\/li>\n<li><strong>Sensitivity:<\/strong> adjustable onboard potentiometer<\/li>\n<li><strong>Main components:<\/strong> YG1006 phototransistor and LM393 comparator<\/li>\n<li><strong>Spectral range:<\/strong> 760\u20131100 nm (as stated in the source listing)<\/li>\n<\/ul>\n<h4>How it works<\/h4>\n<p>The YG1006 phototransistor senses infrared radiation. The LM393 comparator converts the detected level into a digital output, while the analog output provides a varying signal. The source listing states that the digital output is HIGH when a flame is detected and LOW otherwise; verify the output polarity on your particular module.<\/p>\n<h4>Applications<\/h4>\n<ul>\n<li>Flame and fire-detection projects<\/li>\n<li>Infrared-source detection<\/li>\n<li>Arduino, Raspberry Pi and ESP32 experiments<\/li>\n<\/ul>\n<p>This
