Fire Sensor (Hamamatsu UVTRON)

Fire Sensor (Hamamatsu UVTRON)

UVTRON Hamamatsu R2868 is a sensor that detects a flame fire that emit ultraviolet light. Ultraviolet light emitted from a candle flame is a 5 meter can be detected by this sensor. This sensor can also detect some unseen phenomena such as high voltage transmission.

In order for this UVTRON sensors to connect to the system microcontroller then required a series of lawyer-signal condition that serves to change the response of UVTRON into pulses that can be recognized by the system microcontroller. With Module C3704 UVTRON response will then be processed into about 10 pulses mS and the maximum current 100mA. The output module uses the open configuration collector.
