Base Controller
 
The brain of the operation. ESP32 with custom PCBs, designed to handle the outdoor environment.
Installation
 
The actual installation in Peru.
 
Water tanks and sensors in place.
Building the Sensors
 
One of the sensor nodes in action. Each node includes flow sensors for monitoring water usage and pressure sensors for tank level monitoring.
 
 
PCB layout and assembly process. Custom design for reliability. Made some mistakes along the way, but learned a lot.
Schematics
 
 
 
Custom PCBs designed for reliability. Made some mistakes along the way, but learned a lot.
The system works, but there’s always room for improvement.
