IoT Based Air Quality Index Monitoring with ESP8266 & MQ135

May 08, 2020· MQ135 Air Quality Sensor. The MQ-135 gas sensor senses the gases like ammonia nitrogen, oxygen, alcohols, aromatic compounds, sulfide and MQ-3 gas sensor has a lower conductivity to clean the air as a gas sensing material. In the atmosphere, we can find polluting gases, but the conductivity of the gas sensor increases as the concentration of polluting gas increases.

Air Quality Sensor with Carbon Monoxide reading ...

You can pickup a ESP8266 NodeMCU microcontroller from Amazon for like $4. Here's a great overview of the module. Get a CO sensor and your CO2 sensor from Sparkfun. Most environmental quality sensors use eCO2 (equivalent) rather than measure CO2 directly. The BME680 is one such sensor. It'll give you eCO2, VOC, temperature, humidity, and ...

I made a WiFi Carbon Monoxide Detector! : esp8266

An odd mix of really good stuff and consumer grade junk. A DIY CO detector could easily be superior to the run of the mill consumer device. A lot of really useful features could be added in software too, like chirping if the level was subcritical but rising fast, or subcritical but persistant, or a different alarm for supercritical situations ...
