Infrared Flame Sensor Temperature Module 4 Channel Relay Module The dots are waterproof andThis is an Infrared Flame Sensor Temperature Module. A Flame Sensor module, also known as a Fire Sensor module, is a small electronic device that can detect a fire or other bright light sources. This sensor detects IR (Infrared) light wavelengths ranging from 760 nm to 1100 nm emitted by a fire or light source. It has four pins (A0, D0, Gnd, and Vcc) and can be used with Arduino and other microcontroller boards. Features High Photosensitivity Fast
