There are multiple ways to detect a fire, like detecting temperature change, smoke detection, etc. In all of these, detecting temperature change would be more accurate, since some fires won\u2019t even have detectable smoke. Even the temperature measurement is not too dependable since sometimes it\u2019s too late when the change is detected. To overcome this, we can detect the thermal radiation instead of the temperature variation. The easiest and cheapest way to detect thermal radiation is to use a flame sensor. <\/p>\n<p><strong>DL2602Mk05<\/strong><\/p>\n<p>1 x DFRobot FireBeetle 2 ESP32-E<br \/>\n1 x Fermion: 3.5\u201d 480&#215;320 TFT LCD Capacitive<br \/>\n1 x GDL Line 10 CM<br \/>\n1 x Flame Sensor<br \/>\n1 x Crowtail &#8211;
