Upgrading the air quality monitor

When I originally built the air quality monitor for my school I used the Things Network, a public LoRaWAN radio network for low power devices to send data to the internet. This year a new version of the back end came out, called The Things Stack (aka V3). As a result, they are shutting downContinue reading “Upgrading the air quality monitor”

Creating another TTN Mapper node with a Heltec LoRa32 v2

For my Gold DofE practice expedition I used the school’s Things Uno board to make a Things Network node that transmits its GPS coordinates. These GPS coordinates can then be received by gateways, and from there they are used to map the coverage of the Things Network, a free-to-use radio network designed for low powerContinue reading “Creating another TTN Mapper node with a Heltec LoRa32 v2”

Creating a TTN Mapper GPS node with the Things Uno

Recently I went on a DofE expedition in the Brecon Beacons. I wanted to try mapping any LoRaWAN coverage while I was there using TTN Mapper, but we weren’t allowed our phones so I couldn’t use the app. However, TTN Mapper also allows you to use nodes that broadcast their GPS coordinates, thus removing theContinue reading “Creating a TTN Mapper GPS node with the Things Uno”

The Things Certification

In this year’s Things Conference, the ‘Things Certification‘ was launched. It is designed to test your knowledge around the LoRaWAN specification, configuration and implementation. Currently there are four certificates available, and you have to do a 30-minute multiple choice test for each. Usually they cost €99 each, but they are free until the first ofContinue reading “The Things Certification”

Designing and building an air quality monitor

Around a year ago the headmistress of the school asked if it would be possible to build a device capable of monitoring the air quality around the school in real time. The computer science teacher directed her to me and I was asked to do some research and put together a shopping list of theContinue reading “Designing and building an air quality monitor”
