Air Quality Guide

What each measurement means and current live values
This page explains each sensor reading, how it is classified, and the reference ranges behind the classification.
Values are indoor comfort & air-quality references for guidance only — not legal/regulatory limits.
💨 eCO₂ (ppm)
— —
▼
eCO₂ = equivalent CO₂ estimated by the ENS160 sensor from volatile compounds (not a direct NDIR CO₂ measurement). Raised indoor values usually mean less fresh air.
ENS160Measured by the ENS160 sensor. Ideal: below 800 ppm indoors.
Recommended action: open windows / ventilate when it stays above 1000 ppm.
🧪 TVOC (ppb)
— —
▼
TVOC = total volatile organic compounds (paints, cleaners, cooking, new furniture). Open windows / ventilate when high.
ENS160Measured by the ENS160 sensor. Ideal: below 220 ppb indoors.
Recommended action: ventilate and remove the source (paint, cleaner, solvents).
🌿 AQI (1 – 5)
— —
▼
AQI is derived from TVOC levels: the higher the TVOC, the worse the air quality level.
ENS160Derived by the ENS160 sensor from TVOC. Ideal: Level 1–2 (Good).
Recommended action: ventilate and find the pollutant source when the level is 4–5.
💧 Humidity (%)
— —
▼
Thailand bedroom context for a naturally ventilated tropical room — not a legal or health standard. Humidity around 65–80% can be commonly observed in humid weather, but prolonged high humidity can still favour mould.
AHT21 Measured by AHT21. Dashboard context: 50–65% moderate, 65–80% humid, 80–85% high, ≥85% very high.
Recommended action: ventilate when the room feels damp; at ≥85% RH, check for persistent dampness and mould risk.
🌡 Temperature (°C)
— —
▼
Thailand bedroom context for a naturally ventilated tropical room — not a universal comfort or legal standard. Temperature is also affected by airflow, humidity, sunlight and activity.
AHT21 Measured by AHT21. Dashboard context: <26°C cool, 26–32°C typical, 32–35°C hot, ≥35°C very hot.
Recommended action: increase airflow or cooling as temperature rises; ≥35°C is treated as very hot on this dashboard.
📶 Wi-Fi RSSI (dBm)
— —
▼
Wi-Fi signal strength reported by the device on the last sample. A weak link can delay data uploads and trigger a WIFI_WEAK alert.
ESP32Signal delivered by the ESP32 Wi-Fi module. Higher (closer to 0) means a stronger link.
Recommended action: move the device closer to the router or improve the signal when below −71 dBm.
