Fire detection using the scattered light principle with a staggered activation of a further LED unit for radiating in further light pulses with different wavelengths and scattered light angles

Various embodiments may include a method for fire detection comprising: radiating light at a first wavelength into a scattered light volume and measuring a radiation intensity generated by forward scattering; radiating light at a second wavelength and measuring a second scattered radiation intensity...
