Clear thinking for cleaner shared air

Halcyon Signal is a practical publishing project from ESGEN SPAC for teams that manage vape detection, air monitoring, and response plans in shared buildings.

Why this site exists

Vaping in a shared building affects air quality, operations, privacy, guest or staff comfort, and team workload. Workplaces, hotels, schools, housing, and public venues need plain facts that help them ask better questions before they buy tools or set rules.

Halcyon Signal meets that need. We cover how teams place sensors, route alerts, explain policy, and use the data with care.

Floor plans, sensor, and tablet used to plan vape detection across several building types — Good programs start with a plan for each site, not just a hardware list.

Editorial priorities

Respect privacy in sensitive shared spaces.
Treat alerts as context, not automatic proof.
Connect detection to prevention and support.
Use clear language for staff, guests, students, and visitors.
