The 5-Channel Flame Sensor Module uses five infrared photodiodes (light sensors that respond to the specific wavelength of a flame) arranged in a circular pattern to detect fire across a field of view greater than 120 degrees at approximately 50cm distance. The 5 channel flame sensor covers a much wider area than a single-channel module, which means robot or safety system catches flame sources on the sides, not just directly ahead.
A non-obvious fact is that the sensor responds to any infrared source in its detection range, including incandescent bulbs and sunlight, so avoid bright ambient light during testing. The flame detection sensor gives both analog and digital outputs, but the analog output lets you measure how strong the IR signal is, not just whether a flame exists. One honest limitation is that detection distance drops sharply beyond 50cm.
The 5-channel flame detector sensor connects to Arduino for robotics club builds, school fire safety demos, and maker projects. Connect the five signal pins, VCC, and GND to start. StemVolt provides this sensor with trusted quality, ensuring reliable performance and easy usability.
