About Johan Viljoen
Sharing environmental monitoring across air, aquatic & ocean systems
Support independent environmental monitoring and science outreach in Cornwall. Donations help fund website infrastructure, low-cost sensors, and educational resources. My current goal is to upgrade my website and acquire an AirGradient outdoor air quality monitor to explore and openly share air quality observations and educational resources for the under-monitored West Cornwall region, helping support greater awareness and data-informed community decision-making.
