A monitor of soil moisture using an M5StickC
This is intended to be used with a grove moisture sensor. The M5StickC will record the maximum moisture level ever seen and then normalize readings based on this value, expressed as a percent. Every 24 hours the current value is recorded resulting in a history of moisture readings over the last seven days.
When the moisture level drops below a set level (indicated by the red line) a red LED will flash once a second.
