Story

This is an open-source programmable watch that supports development in C or Python, allowing for the addition of new features at any time.

It is primarily used for environmental monitoring, alerting users to open windows for ventilation or go outside for fresh air when air quality is poor, to prevent discomfort.

For environmental monitoring, it uses two Sensirion sensors, the SGP40 and the SHT30. It also features a ws2812 led and a buzzer for audio-visual alarm alerts.

It comes with a motion sensor that helps people track their steps. For those with knee issues, it can help control daily step counts to achieve a rest and recuperation goal.

It has a USB Type-C interface, supporting lithium battery charging and file transfer.
