EnviroDIY Monitoring Station 

Basic overview of the 

EnviroDIY monitoring station 

functionality:  

 

• The solar panel charges the 

Lithium Ion Polymer (LiPo) 
battery.  

• The LiPo battery powers the 

mayfly data logger.  

• The Mayfly data logger records 

data collected from the 
sensors.  

• If there is cellular telemetry, the 

cell board sends data to online 
portal 

( MonitorMyWatershed.org).   

Solar panel & 
mounting bracket
