how avalert works

Utilizing metrics gathered from onboard sensors, AvAlert makes a prediction based on data thresholds, stressing emphasis on slope angle. Based on this, AvAlert assigns one of three stability levels: stable, variable, unstable. This risk rating appears as a large colored bar across the screen.

AvAlert stores temperature, slope, and pressure readings over the last several minutes and displays them in trend graphs.
Sudden pattern changes like warming or rapid slope shifts can indicate rising avalanche risk and AvAlert will respond accordingly.

The resistive touchscreen lets the user navigate between the status screen (live metrics + risk bar), slope screen (large angle display), trends screen (graphs), and settings (themes, PRO mode, customization). All pages update automatically in real time accordingly.

Using the magnetometer, AvAlert determines the user’s heading (N, NE, E, etc.). This helps skiers and riders stay oriented on the mountain and understand which aspects (north-facing, south-facing) may be more unstable.

AvAlert continuously collects live information from onboard sensors, including temperature, pressure, humidity, slope angle, direction, and snow depth. These measurements update several times per second.

AvAlert requires no cell service, internet, or GPS. All processing happens on the device using the ESP32-S3 motherboard, making it fast, reliable, lightweight, and suited for avalanche terrain, ski touring, and remote expeditions. The equipment is rated for -40°F, making it perfect for any condition.
