The Okdo TelePort flame sensor, also known as the infrared receiving triode, has two signal pins which can output digital and analog signals respectively. When the sensor detects the flame, the digital signal terminal outputs low levels. It can be used to detect fire or other lights whose wavelength stands at 760 nm ∼ 1100 nm. It is based on the YG1006 sensor which is a NPN silicon phototransistor with high speed andsensitivity. It is also sensitive to the infrared radiation on the grounds of its black epoxy resin. Additionally, it plays an important role in detecting fire source.
