Air Quality Monitoring Pledge Drive

This pledge drive is currently a draft. Please do not contribute yet.

We currently monitor some basic things like temperature, humidity (and soon barometric pressure). These can be queried from Discord or viewed on Cacti. The pandemic notably demonstrated the importance of maintaining good air quality, promoting good ventilation, leading to reduced rates of infections from airborne viruses. There are a few areas where this could be problematic, such as during film nights in the Comfy Area, random food events in the Kitchen, members meetings in the Blue Room, as well as smaller multi-occupancy rooms such as the Craft Room. The hackspace (obviously) also provides access to many tools which generate large amounts of fine airborne particles. Making data about these invisible hazards will allow hackspace members to make informed decisions about their health.

For EMF Camp 2022 and 2024, Graham Sutherland designed and built a number of air quality monitors which were installed across the camp site. Graham has kindly agreed to help with this project by re-using the design. These air quality monitors are equipped with a SHT35 sensor for temperature and humidity, a SCD40 for CO2, and SGP30 for small airborne particle counts. Monitoring CO2 levels in a room the recommended way of managing the spread of airborne viruses such as COVID. The SGP30 will produce counts of PM1.0, PM2.5, PM5.0 and PM10 (varying sizes of particles in the air), as well as a measure of Total Volatile Organic Compounds (TVOCs).

Each air quality monitor will cost roughly £70 and we'd like to run a pledge drive for the construction and installation of these. This includes the board, components and materials to laser cut some enclosures. The following areas have been identified as good locations for sensors:

• Comfy Area
• Blue Room
• Kitchen
• Craft Room
• Dusty Area
• Classroom

Air Quality monitoring is cool on its own, but if you contribute £30 or more to the pledge drive we will engrave your name on one (or more) of the sensors. For the six sensors we've listed above, we are hoping to raise £420. If we raise more than this, we can build additional sensors for areas like the Studio, Electronics Area, one or more for the workshop, etc. These areas are larger and less of a priority.

If you'd like to contribute to the pledge drive, please add your name to the table below, along with the amount you're pledging. If you are unable to login to the Wiki, or struggling to edit the table, please email your pledge to the trustees.

Please do not make your payment until contacted.
