Abstract
A gas sensor having a micro-package structure includes a light-emitting unit, a light-receiving unit, and a signal-processing unit all deposited on a substrate, and a package body fixed to the substrate and having a chamber and a through hole. The chamber accommodates all the units and the through hole is over the substrate. Gas enters the chamber through the through hole. The light-emitting unit emits an optical signal that passes through the gas and then is received by the light-receiving unit. Then a signal-processing unit electrically connected to the light-receiving unit performs spectral analysis. Thereby, the gas sensor is advantageous for requiring low packaging costs and being compact.
