Greywater monitor
International team project · 5 months
Reusing greywater only works if you know it is safe. I did the sensors, wiring and code for a Raspberry Pi Pico monitor that reads pH, turbidity and water level, kept lean so it runs on very little power, averages and calibrates the readings, shows them on an OLED, sounds an alarm when they drift, and locks the outlet with a servo. A Python dashboard plots the data live and logs it to CSV.
Tools: Raspberry Pi Pico, MicroPython, Python, CustomTkinter, Matplotlib, PySerial
