SGAS707
Datasheet
Description
The IDT SGAS707 is a solid-state chemiresistor sensor designed to detect volatile organic chemicals (VOCs) in air. The sensor uses an integrated heater with highly sensitive polymer-MOx composite material designed for detection of VOCs.
The chemiresistor sensors in the IDT SGAS family are based on the principle that metal-oxide materials undergo surface interactions (physisorption and chemisorption) with gas molecules at elevated temperatures, resulting in a measurable change in electrical resistance. As metal-oxide materials are polycrystalline (i.e., composed of multiple grains with distinct grain boundaries), the adsorbed gases have significant electronic effects on the individual grains.
