For Arduino Boards (&ESP32). Additional Examples/Commands., Hardware/Software Serial

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

Example for Node IoT use RAK3172

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.

💨 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.
