Smart alarm system for indoor agriculture
* Thanks for the source code and project information provided by @Huixiang Wee
Story
Driving question: How can we make up for the lack of manpower in the agricultural sector.
The agricultural sector faces a lack of manpower, and we want to use the m5stack to reduce the need of manpower by using it to detect hardware errors

Code
Smart Alarm System For Indoor Agriculture Python
An alarm will sound when there is a significant deviation between expected values and sensor values. or if the system cannot correct minor deviations in value. It will also suggest possible hardware errors that could cause the error.
