OCTOPUS Flame Sensor is a module based on the infrared receiver (IR probe), simple in design, light, convenient, and very sensitive. It can be used to detect the source of fire, make simple fire-fighting robots, produce fire alarms, and so on.

Note that the infrared sensor operating temperature is generally from -25 degrees to 85 degrees, therefore, in order to avoid damage, in the process of use, maintain a suitable distance from the flame probe to the flame, not too near.

Three pins electronic building blocks interface: input 5V – GND. S for signal output.
