Use germanium or silicon windows for through-glass detection.<\/li>\n<li><strong>What is the maximum detection range of a PIR sensor?<\/strong> Typically 5\u201312 meters for standard modules; up to 30 meters with Fresnel lens arrays.<\/li>\n<li><strong>How do I calibrate an IR temperature sensor?<\/strong> Use a blackbody calibrator at known temperatures (e.g., 25\u00b0C and 100\u00b0C). Adjust offset and gain via software.<\/li>\n<li><strong>Are IR sensors affected by sunlight?<\/strong> Yes, direct sunlight contains strong IR components. Use optical filters (e.g., 8\u201314 \u03bcm bandpass) to minimize interference.<\/li>\n<li><strong>What is the accuracy of IR thermopile sensors?<\/strong> \u00b10.5\u00b0C to \u00b12\u00b0C depending on model and measurement distance (typical for MLX90614).<\/li>\n<li><strong>Can I use IR sensors in explosive environments?<\/strong> Yes, select intrinsically safe models with ATEX or IECEx certification (e.g., Honeywell 495i series).<\/li>\n<li><strong>What is the minimum detectable temperature?<\/strong> Most thermopile sensors detect from -40\u00b0C to +300\u00b0C; specialized models go to -70\u00b0C (e.g., Heimann HTPA32x32d).<\/li>\n<li><strong>How do I interface an IR sensor with Arduino?<\/strong> Use I2C or analog pins. For MLX90614, connect SDA\/SCL to A4\/A5, install Adafruit library, and read temperature via serial monitor.<\/li>\n<\/ol>\n<h2 id=\"toc-10b3ccf0988185b15871f8d0236e5fb3\">\uc870\ub2ec \uace0\ub824 \uc0ac\ud56d<\/h2>\n<p>When purchasing IR sensors, evaluate these critical factors:<\/p>\n<ul>\n<li><strong>Wavelength Compatibility:<\/strong> Ensure the sensor&#8217;s spectral range matches your application (e.g., 8\u201314 \u03bcm for human body detection, 3\u20135 \u03bcm for high-temperature industrial).<\/li>\n<li><strong>Field of View (FOV):<\/strong> Standard FOV is 90\u00b0\u2013120\u00b0 for PIR sensors. Narrower FOV (10\u00b0\u201330\u00b0) is available for focused detection.<\/li>\n<li><strong>Output Interface:<\/strong> Choose between analog (0\u20135V), digital (I2C\/SPI), or PWM based on your controller compatibility.<\/li>\n<li><strong>Environmental Rating:<\/strong> For outdoor use, select IP65 or higher. For food processing, require IP69K for high-pressure washdown.<\/li>\n<li><strong>Warranty and Support:<\/strong> Chinese manufacturers typically offer 12\u201324 months warranty.
