Build your own accurate air quality monitor with the build instructions below. You can either source the components yourself or get a ready-to-build kit from our online shop.
You can use it with the AirGradient data platform or connect it to other platforms like Home Assistant or HomeKit. More information on our Integrations Page.
Professional and highly accurate air quality monitor built measuring PM1, PM2.5, PM10, CO2, TVOCs, NOX, temperature and humidity. Board allows a lot of extensibility for other sensors e.g. barometric pressure.
Professional and highly accurate outdoor air quality monitor built measuring PM1, PM2.5, PM10, CO2, TVOCs, NOX, temperature and humidity. Fully weatherproof enclosure.
The AirGradient ONE comes with multiple mounting and cable-management options, making it a flexible air quality monitor that can be mounted on a wall or sat on a desk (using the included feet).
Read MoreThe AirGradient Open Air comes with a mounting bracket on the back of the device designed to allow flexibility during the mounting process. Whether you want a permanent or temporary installation, you can set up the Open Air how you want.
Read MoreWe are continuously updating our open hardware / open source air quality monitor kits and as a results have different versions of the built instructions.
Read MoreThis page helps in reading out data directly from the AirGradient monitor. For good error analysis, please log at least 3 minutes of data.
Read MoreWe use the PMS5003T version for our outdoor monitor Open Air which includes an integrated temperature and humidity sensor. If you use the Arduino Sketch from the AirGradient Arduino library you need to patch the PMS library to get these values.
Read MoreConnecting the monitor to the AirGradient Dashboard is a two-step process. You need to connect your monitor to the WiFi network and register it on the dashboard.
Read MoreWhen we launched our indoor classroom monitoring with our professional sensors, one of the first feature request from teachers was to have a small display that would show the indoor and outdoor air quality.
Read MoreJust a quick shout out that we have 3D printer files to print your own enclosure. It fits the DIY PCB perfectly and consists of a top and bottom part that snap together.
Read MoreHere we want to give an overview of current and out-of-production AirGradient monitor models. Current Mainline Models These models are the main products of AirGradient and under the CC-BY-SA open-source hardware license.
Read MoreThe accuracy of an air quality monitor is impacted by a variety of internal and external factors, for example: Enclosure: The ventilation and internal placement of sensor modules can greatly impact their accuracy.
Read MoreWe strongly recommend that you fully understand data ownership terms before buying an air quality monitor, as some of them can be extremely restrictive.
Read MoreThere are a few batches of Plantower PMS5003 sensors that -although within specs- show quite low values in low PM concentrations.
Read More1. Introduction This policy outlines the security considerations and procedures for deploying AirGradient air quality monitors (specifically models like the AirGradient ONE (I-9PSL) and AirGradient Open Air (O-1PST)) within school or enterprise networks.
Read MoreStep 1 Plug in the air quality monitor Step 2 All current air quality information is on the screen on the monitor.
Read MorePlease note that these firmware versions do not support the D1 mini (ESP8266) based models DIY Pro or Basic kit but we currently work on an update that will bring as many as possible of the new features to the D1 mini.
Read MoreBelow are custom firmwares for very specific applications and not for general use.
Read MoreThese instructions are for the people who ordered our first batch of the new DIY kit with the professional enclsosure. The instruction assume that you have already built a normal AirGradient DIY kit and thus primarily focus on the differences to the default DIY Kit.
Read MoreFor the new AirGradient monitors we use the ESP32-C3-MINI microcontroller. This tutorial explains you how to set up the Arduino IDE for this microprocessor in order to flash the software.
Read MoreFor all the old versions of the AirGradient build instructions the Wemos D1 Mini microcontroller was used. This tutorial explains you how to set up the Arduino IDE for this microprocessor in order to flash the software.
