Integrated Device Technology, Inc. is enabling manufacturers to add new odor detection and mitigation capabilities to their smart refrigerators with the introduction today of the IDT ZMOD4450 refrigeration gas sensor platform, the first integrated digital gas sensor for Refrigeration Air Quality (RAQ) applications. The ZMOD4450 can detect the gases produced by spoiling fruits, vegetables, meat or dairy products and enables smart refrigerators to post alerts on their door-mounted displays, notify users via their smartphones and even trigger active deodorizing systems.
The ZMOD4450 is software configured to sense a wide variety of gases that produce odors, affect food taste or cause foods to spoil prematurely. Early detection of these gases – ethylene, hydrogen sulfide, dimethyl sulfide, trimethylamine and more – enables consumers to identify and discard spoiled food before it affects other foods. For example, ethylene produced by an overripe piece of fruit will accelerate the ripening of nearby fruit.
Every ZMOD4450 sensor is calibrated with ethylene to ensure consistency from lot to lot, an important advantage for manufacturers with long production runs. ZMOD4450 devices offer best-in-class reliability as a result of receiving complete qualification for harsh use cases – such as siloxanes – and from an unprecedented life characterization.
The ZMOD4450 is the newest member of IDT’s ZMOD family of gas sensors.
