Smoke
detector
What is a smoke detector?
A smoke detector is used to sense smoke in smart
buildings.
What are the key parameters offered by ST products?
• Low input bias
• Low power
• Tiny DFN8 package (2 x 2 x 0.6 mm)
Small smoke particles inside the chamber scatter light
from the LED into the photodiode. The current generated
by the photodiode is amplied by an op amp.
