3.3 Operation Principle
The detector uses two pyroelectric infrared sensors to detect the change of light signal
of flame and background light signal at two bands of infrared spectrum through two
signal processing channels. Its microprocessor analyzes the signal through the flame
channel and background channel to judge if there is flame.
