Helium Air Quality Sensor

A Helium-based air quality sensor and solar setup.

As environmental concerns and awareness increase, I decided to build and deploy an array of wireless, self-contained, weather-resistant, solar-powered air quality sensors, also known as WSPAQS. The sensor array measures CO2 levels and VOCs. (What’s a VOC, you ask? See below as it’s rather long.) It also has a voltage/current sensor to keep track of the solar charge.

We will be using an Arduino Uno, a Raspberry Pi 3, Helium Starter Kit, my board, an Adafruit 6 volt solar panel a 24 VAC/VDC portable power converter to USB board (design files attached), and a hacked portable battery pack to build an awesome sensor setup that will transmit the data to Librato.”
