Enviro for Raspberry Pi – Enviro

Monitor your world with Enviro and Enviro + Air Quality for Raspberry Pi! There's a whole bunch of fancy environmental sensors on these boards, and a gorgeous little full-colour LCD to display your data. They're the perfect way to get started with citizen science and environmental monitoring!

Monitor your world!

Enviro + Air Quality is designed for environmental monitoring, and lets you measure air quality (pollutant gases and particulates*), temperature, pressure, humidity, light, and noise level. When combined with a particulate matter sensor*, it's great for monitoring air quality just outside your house (more information below) and lets you contribute your data to citizen science efforts to monitor air quality via projects like Luftdaten.

Enviro is designed for indoor monitoring, letting you measure temperature, pressure, humidity, light, and noise level. It's great for keeping tabs on what's going on in rooms in your house, office, or elsewhere. Push the data to server and you can view the data remotely from anywhere.

Citizen science with Enviro + Air Quality

We've developed Enviro + Air Quality in collaboration with the University of Sheffield, with the aim of letting you contribute real-time air quality data from your local area to open data projects like Luftdaten.

The alarming drop in our air quality is something that's really important to understand. Devices like Enviro + Air Quality allow fine-grained, detailed datasets that let us see shifts in air quality through time and across different areas of cities. The more devices that contribute data, the better quality the dataset becomes.

Particulate matter (PM) is made up of tiny particles that are a mix of sizes and types, like dust, pollen, mould spores, smoke particles, organic particles and metal ions, and more. Particulates are much of what we think of as air pollution. They can be measured, in size and quantity, by particulate matter sensors like the PMS5003 that you can connect to Enviro + Air Quality.

The analog gas sensor can be used to make qualitative measurements of changes in gas concentrations, so you can tell broadly if the three groups of gases are increasing or decreasing in abundance. Without laboratory conditions or calibration, you won't be able to say "the concentration of carbon monoxide is n parts per million", for example.

Temperature, air pressure and humidity can all affect particulate levels (and the gas sensor readings) too, so the BME280 sensor on Enviro + Air Quality is really important to understanding the other data that it outputs.

Indoor monitoring with Enviro

Enviro is designed especially for indoor monitoring. The temperature, humidity, light, and noise readings can be used to keep track of conditions in your home and, combined with the LCD to display the data and the proximity sensor for interaction, it makes an ideal headless monitoring device.

Why not combine it with some IoT smarts like an Alexa skill so that you can ask what the temperature or humidity is? Or you could set up a trigger action with IFTTT that turns your Philips Hue lights on when the light level drops below a certain level. There's loads of possibilities!
