Flame Sensors operate by detecting the infrared radiation emitted by flames. When exposed to flames, the sensor generates an electrical signal, triggering an alert or response in a connected system.

Flame Sensors find applications in various industries, including home safety systems, industrial automation, and commercial buildings. They are often integrated into fire alarm systems, gas appliances, and other fire detection devices.

The Flame Sensor Module is designed to identify fire/flame sources or other light within the wavelength range of 760nm – 1100 nm. It utilizes the YG1006 sensor, a high-speed and highly sensitive NPN silicon phototransistor. It's important to note that sunlight can affect the sensor's performance.

Interfacing a Flame Sensor with a microcontroller or Arduino involves connecting its output to the digital input pin of the controller. The sensor provides a digital signal that can be processed by the microcontroller to trigger specific actions.
