The Forest Fire Finder system aims to reduce the time between a fire being started and authorities receiving an alert. The idea is that the longer the fire goes undiscovered, the bigger it gets, until uncontrollable situations develop, such as the Victorian fires.
The system monitors fires up to 15km away. It carries out a chemical analysis of the atmosphere by looking at the colours of the sky and building a spectro graphic. Sky containing smoke will be different to clear sky. Also, different types of smoke absorb light differently, meaning that the spectro graphic will be different, so that the system can filter out false alarms.
The system will only have a false alarm about every five days, according to the company, which it claims is better than the competition — the competition sees false alarms occur every single day. The system also takes information from temperature, humidity, wind direction and speed, atmospheric pressure and rainfall atmospheric sensors.
