SparkFun Refrigeration Gas Sensor - ZMOD4450 (Qwiic)

The ZMOD4450 gas sensor from Renesas is a unique Refrigeration Air Quality sensor designed to measure gases emitted by food ripening or rotting: ethlyene, amines and volatile sulfur compounds. The sensor can measure Ethylene (C2H4), Trimethylamine (C3H9N) and Dimethy sulfide (C2H6S) in air with up to ±10% repeatability and with additional calibration using a known organic compound can be accurate to ±15%. With the ZMOD4450 you can finally quantify that funky smell coming from your refrigerator.

The ZMOD4450 firmware is closed-source so you will need to create an account with Renesas and agree to their terms prior to accessing any programming information or the firmware. The Renesas ZMOD4450 product page has links to get you started with their firmware.
