EC_Salinity Probe Interface
Monitor hydroponic nutrient levels, salinity in aquariums, the ocean, or pools, measure soil salinity, monitor water quality
- Electrical Conductivity in Siemens
- Total Dissolved Solids in PPM
- Salinity in PSU and PPT
What it is
An ATTiny85 programmed as an I2C slave, a DS18B20 waterproof temperature probe, and a two-electrode EC probe. It measures conductance and converts it into a temperature-compensated Siemen. From that value, it derives PPM and salinity. It is accurate to ~0.5mS in seawater, and to within ~0.05mS in the hydroponic or freshwater range.

This is a PlatformIO project. Download and install it, import this repo, and it should download all the required tools for you. It expects a USBTiny device to upload the firmware.
