## Description

JESSINIE MICS-6814 Gas Sensor Module Air Quality Detection Sensor Carbon Monoxide CO Nitrogen Dioxide NO2 Ammonia NH3 Gas Detector Module for Arduino - desertcart.com

Review: not worth it. - No usable documentation. I one asks specs for the chip itself are provided but no information how to use it in programming.
Review: It Works But Requires Research - This module does work once you locate the documentation online. However, the real challenge is testing it. You need a trigger to properly read the analog values. I just went down into the garage and ran some equipment (with the door open). Cool module once you get it going!
