OTA updates made slick and simple for everyone!

Reads and writes data (e.g. power, mode, fan status etc.) from/to a Mitsubishi Heavy Industries (MHI) air conditioner (AC) via SPI controlled by MQTT

Arduino-based WiFi/MQTT controller for wireless operation of a Mitsubishi Heavy Industries air conditioner through its serial CNS port

Arduino Uno, 433MhzRx and OS WMR86 Weather Station

An advanced CO2 Monitor/Meter firmware for ESP32 with Android and iOS App for real time visualization and charting of air data, data logger, a variety of communication options (BLE, WIFI, MQTT, ESP-Now) and many supported sensors.

AB protocol decoder for toshiba air conditioners

Erriez MH-Z19B and MH-Z19C CO2 sensor library for Arduino

Air quality sensing and monitoring

Detects air particulate matter (PM - pm1, pm2.5, pm10) concentrations and sends data to an MQTT server. An alternative firmware for ESP8266 devices like the NodeMCU board written for Arduino IDE and PlatformIO

W A R N I N G: This is a previous proof of concept of CanAirIO device firmware over a TTGO T-Display board, but now it is only a old reference. The last stable version of CanAirIO device already have support for this board and many features more. Please use the official CanAirIO Firmware instead of this firmware. https://github.com/kike-canaries…

MQTT Air quality (PM10, PM2.5) monitoring station

Read data from a Mitsubishi Heavy Industries air conditioner and send the data via MQTT via ESP8266

ESP8266 Indoor Air Quality Monitor

Measure temperature and humidity with the Sensiron SHT3x sensor.

Two-phase air/water flow in contact with atmospheric pressure and enclosed by walls. Simulation requires openFoam to run.

This is our course homework. I create a physical simulation program to demonstrate the dynamics of human hair under the influence of air flow.

Simple air quality monitor with CO2, temperature and humidity sensors. Based on MSP430 + Energia

A C++ library for ESP8266 for load and parse data from DWD about pollen types in the air.

Combination of air quality monitor & DCF77 clock.

Senses the temperature, humidity and gaseous component (in ppm) of the surrounding air. It links to thinkspeak and analyses it.
