Monitor air quality with your AeChai Air Quality Monitor. Get PM2.5 & PM10 readings, WHO-based health ratings, and send SOS alerts to your guardians instantly.
AeChai connects to your personal air quality monitor via Bluetooth to give you real-time PM2.5 and PM10 particulate matter readings right on your phone.
REAL-TIME AIR QUALITY MONITORING
Pair your AeChai Air Quality Monitor and view live air quality data on your dashboard. Readings are classified using the WHO 2021 Global Air Quality Guidelines into six health categories: Good, Fair, Moderate, Unhealthy, Very Unhealthy, and Hazardous.
SOS EMERGENCY ALERTS
When air quality becomes dangerous or you feel unsafe, press and hold the SOS button to instantly alert your trusted guardians. AeChai sends an SMS with your name, location, and a live tracking link so your guardians can find you.
LIVE GUARDIAN TRACKING
During an active SOS, your GPS location is streamed in real time to a secure web page that guardians can access directly from the SMS link. When you mark yourself as safe, location sharing stops immediately.
GUARDIAN MANAGEMENT
Add up to five trusted guardians with their Ghana phone numbers. Import contacts directly from your phone for quick setup.
