CanAirIO is a citizen science community using mobile and fixed sensors to measure air quality with cell phones and low-cost technology. This is an Open Source initiative that uses a ESP32 module and some air quality sensors, interfaced with an Android client app to have fixed (WiFi) or mobile (Bluetooth) air quality stations.

CanAirIO Bike try to motivate collaboration from cyclists or people that use it to have mobile tracks of air quality. We have two new device versions, CanAirIO bike with PM2.5 sensors (Sensirion SPS30) and CanAirIO CO2 (Sensirion SCD30), the latter for sensing the right ventilation in indoors to reduce COVID-19 risk.

Features

These devices able to work in standalone mode without clouds, apps, Bluetooth, WiFi, etc. but also you could have the next features:

CanAirIO Firmware:

  • Super easy web installer, via Chrome or Edge
  • Mobile station (via Bluetooth LE for tag GPS variables)
  • Fixed station, (using only your WiFi)
  • Fast WiFi credentials provisioning via Bluetooth
  • PAX Counter (detect people around of device)
  • Automatic firmware OTA updates (stable/testing channels)
  • Share mobile tracks via mobile.canair.io or CanAirIO app
  • Home Assistant integration, discovery and multisensor support
  • Share your fixed station quickly via Anaire cloud
  • Custom InfluxDb alternative: Store all data in your own instance
  • Separated sensors layer for improve support of new sensors
  • Multiple boards and sensors support with only one firmware
  • Some built-in functions: Brightness, AQI graph, sample time, Wifi On/Off, calibration, etc.
  • CanAirIO is Open-Source / Open-Design / Open-Access

NOTE: Supporting our Citizen Science Initiative many people be able to fight for air quality rights in many countries with air quality problems. More info in CanAir.IO

  • CanAirIO CLI preview

    Hpsaturn08/31/2023 at 20:04 0 comments

    While searching for alternatives to configure the CanAirIO Firmware, and also to provide an option for those without Android Phones, for instance for iOS and Chrome users, I developed a CLI tool. This CLI tool is capable of configuring numerous parameters within the current firmware.

    For example here the CLI is used to configure the OLED screen behavior:

  • CanAirIO was ported to M5Stack Devices

    Hpsaturn02/10/2022 at 23:39 0 comments

    canairio_m5stickcplus full video

    Overview

    CanAirIO for M5Stack devices contains special support for these kind of boards and devices. In this development we are trying to improve an easy way on the building of mobile and fixed stations for CanAirIO Air Quality network.

    Advantages

    CanAirIO M5Stack devices

    Plus the current features of CanAirIO firmware, the M5StickC Plus has the next extra features:

    • Dual I2C port (Hat and M5 grove port). You can connect multiple sensors. For example one EnvII hat and three sensors via grove port plus grove hub
    • Compatibility with internal I2C devices, for example in the M5CoreInk and M5StickC Plus, the internal I2C handled the real time clock and the power unit, the CanAirIO Sensors Library works without conflicts swapping this channel with the hat channel for reach three I2C channels at the same time.
    • M5Stack has a wonderful feature, 5V output, it reduce the complexity of the DIY creation, because we need 5V for example for particulate meter sensors and old UART devices. In comparasion for example to CanAirIO Bike, it is a improvement on the build work.
    • Enclosures and expansion ports. Like we mentioned, M5 has for example DIY box or expansion ports for reduce the complexity in the wiring and the connection.

    CanAirIO Sensors Lib DEMO with M5CoreInk

    M5CoreInk Multi Sensor

    This project use the CanAirIO Sensors Library to have a complete air quality device. Thanks to this library you able to have many posibilities of sensors and variables automatically, for example you can connect one CO2 sensor or the combination of it with particulate meter sensors (PM2.5) or environment sensors (T, H, P, Alt, etc). The library able to detect and select each driver and third party library for handling these sensors and give you the complete list of variables with a few lines of code. Please see the demo video.

    Also the installation of this firmware in your device is possible only with one click via an easy Web installer without WiFi or compiling anything.

    Features

    • Multi variable - multi sensor support with auto configuration
    • CO2 sensor calibration via wheel button
    • Continuous mode or low power consumption mode
    • Automatic sensor refresh interval on USB connection
    • Partial update (fast refresh without blink) in USB mode
    • Support two I2C channel (Hat or external port).
    • Auto selection of sample time by sensor type
    • Low power consumption in Battery mode (Deep sleep via RTC)
    • Able to set beep alarm for PM2.5 or CO2
    • Redraw complete screen and first setup via middle button
