Arduino imeplementation for CO2 sensors of the MH-Z series (Intelligent Infrared CO2 Module)

Data acquisition and logging for Air Quality Sensors with UART interface

💥 Arduino library for Winsen MH-Z19 – infrared carbon dioxide sensor. The library allows using the sensor over hardware or software UART on any board that supports Arduino.

Native Apple HomeKit via an ESP32 for the IKEA VINDRIKTNING PM2.5 Air Quality sensor + MH-Z19B CO2 Sensor

[ES] Dispositivo simple para medición de CO2. [EN] Simple device for CO2 measurement.

💨 A collection of tiny and ultra-cheap web things for monitoring air quality. The devices measure: temperature, humidity, barometric pressure, the concentration of carbon dioxide, dew point. The devices easily integrate into the Web of Things ecosystem and can be used indoor or outdoor.

Circuit that recognizes the amount of CO2 in a room. Built with the ESP8266 µC and a MHZ-19B sensor.
