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.
An Arduino-compatible library is provided to make using the probe easy and there is extensive documentation on the use and setup of the device. The library is available for download and installation in the Arduino Library Manager as well as the PlatformIO Library Manager, just search for EC Salinity.
There is also a python3 library available for use on the Raspberry Pi. You can find it at the library’s GitHub page.
