As an optical module designed for smoke and aerosol detection, the Analog Devices ADPD188BI uses dual wavelength technology to differentiate a nuisance source from a real smoke source. Watch a live demonstration of the ADPD188BI in action in this video from Analog Devices.
The Analog Devices ADPD188BI integrates two light emitting diodes (LEDs) and two photodiodes (PDs) as a complete photometric system for smoke detection. In this video from Analog Devices, a demonstration of this dual wavelength optical module shows how the ADPD188BI can detect real smoke and reject a nuisance source by differentiating different particle sizes.
