How is a different ionization detector with smoke, infrared, or heat detector? help!
A smoke detector may be either photoelectric - with smoke particles reflect light that is detected - or ionizing radiation, where a small radioactive source creates a load and the ionized gas from the landfill fire, it can be detected.
A pure ionization detector would work the same as this one.
An infrared sensor uses a material that is sensitive to heat radiation in the infrared to produce a small current, then two or more pieces of material are checked for changes in relation to others as a person moving past the way.
A thermal detector, as if the fire would require a higher level of activation of the infrared and would involve a time factor - there is a minute of reading 110 degrees, 150F now, etc.
