Continuous = fan always on, 1-minute posts. Use for decay tests and smoke events. Duty = sensor sleeps between samples; use for long-term deployment. The node picks up changes on its next post (≤1 min in continuous mode, next wake in duty mode).
Corrected PM2.5 uses the EPA/Barkjohn extended piecewise equation (the AirNow Fire and Smoke Map correction: 0.524·CF1 − 0.0862·RH + 5.75 at low concentrations, blending to a quadratic form above 210 µg/m³) with the node's ambient RH. Raw values are what the PMS5003 reported; the database stores raw only. Chart averaging (Avg buttons) is display-only - every raw reading is kept. Data older than 48 h arrives pre-averaged to 10 minutes, so "Raw" on the 7D/30D ranges shows 10-minute points.
