SparkX Refrigeration Gas Sensor - ZMOD4450 (Qwiic)
Discontinued
The ZMOD4450 from Renesas is a refrigeration air quality gas sensor designed to detect gases emitted by food as it ripens or spoils — including ethylene (C₂H₄), trimethylamine (C₃H₉N), and dimethyl sulfide (C₂H₆S). With up to ±10% repeatability, it lets you quantify that funky smell coming from your fridge.
This SparkX Qwiic breakout makes the ZMOD4450 easy to integrate — just plug in a Qwiic cable for solderless I²C connectivity. No voltage regulation or level shifting required.
