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! ## Features - The MiCS-6814 is a robust MEMS sensor for the detection of pollution from automobile exhausts and for agricultural/industrial odors. - Detectable gases: CO; NO2; C2H5OH; H2; NH3; CH4; C3H8; C4H10 - Module power supply voltage: DC4. 9V-5. 1V - Temperature and humidity of working environment: -30 c ~ 85 c 5 ~ 95% RH - Robust MEMS sensor for harsh environments ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BG2YZP5L | | Alarm | Audible | | Best Sellers Rank | #44,909 in Computers ( See Top 100 in Computers ) #610 in Single-Board Computers | | Brand | JESSINIE | | Customer Reviews | 3.7 out of 5 stars 5 Reviews | | Manufacturer | JESSINIE | | Mfr Part Number | MICS 6814 | | Model Number | MICS 6814 | | Number of Items | 1 | | Operating Humidity | 95 percent | | Operating humidity | 95 percent | | Power Source | Battery Powered | | Power source | Battery Powered | | Product Style | Industrial | | Sensor Type | gas sensor | | Sensor type | gas sensor | | Style | Industrial | | Unit Count | 1 Count | ## Product Details - **Brand:** JESSINIE - **Style:** Industrial - **Power source:** Battery Powered - **Alarm:** Audible - **Operating humidity:** 95 percent ## Images ![MICS-6814 Gas Sensor Module Air Quality Detection Sensor Carbon Monoxide CO Nitrogen Dioxide NO2 Ammonia NH3 Gas Detector Module for Arduino - Image 1](https://m.media-amazon.com/images/I/41tVa3szaAL.jpg) ## Customer Reviews ### ⭐ not worth it. *by T***. on 11 January 2024* No usable documentation.
