The goal of this project is to automatise some parts of my pool, mainly the flter pump based on the water temperature. There is also an option to use a ph pump.
The base hardware is an esp32 devkitC. Other hardware:
- Box: arduitouch
- LCD: Ili9341 240x320 RGB touch screen
- Power: Integrated 5V voltage regulator (input voltage 9 - 35V DC)
- Built-in piezo buzzer
- Controler: ESP32 board
- Temperatures (water and ambiant): 2 DS18B20
- Water pressure: GS07381-06 (200PSI) amazon
- RTC: DS3231 amazon
- ADC: ADS1115 az-delivery
- LevelShifter: TXS0108E az-delivery
- Relay: 4-relay module 5V with optocoupler low-level trigger az-delivery
-
The box
-
The pressure sensor on top of the sand filter
- Read/write configuration from preferences (nvs storage)
- Mesure water temperature, ambiant temperature and water pressure
- Auto-detect DS18B20 (temperature sensors)
- Avaluate filtering time based on day hour and water temperature
- Get/Set values through grpc request
- Set time with ntp
- Send data with mqtt
- alarms on temperatures and pressure
- frost protection
- low/high pressure protection
To ease configuration update 2 front-end are under developement:
- CLI: https://github.com/golgoth31/domopool-cli
- UI: https://github.com/golgoth31/domopool-cli/tree/master/web
The local table is defined like this:
