Isolated EC Probe Interface

Monitor hydroponic nutrient levels or salinity in pools.

• Electrical Conductivity in Siemens (0.5 - 20.0 mS/cm)
• Total Dissolved Solids in PPM (250 - 100,000 PPM)
• Salinity in PSU (2 - 12 PSU)
• Temperature in Celsius/Fahrenheit (-55 - 125 C)
• Electrically Isolated

What it is

An electrically isolated I2C sensor device, a waterproof temperature sensor, and an electrical conductivity probe. It measures the conductivity of a solution and converts it into Siemens (S) total dissolved solids and salinity. The firmware allows for single or dual-point calibration with temperature compensation.

The board uses the Qwiic Connect System for wiring, it's an easy-to-use, polarized, push-to-fit connector. No more mistaken connections or soldering header pins.

Running this example

From the /rust folder, type cargo run. You may run into permission issues and need to run the executable with sudo. sudo ./target/debug/ufire_ec_bin. You'll be presented with a > prompt. Type help and you'll get a list of commands you can run to perform various tasks with the board like taking an EC or temperature measurement.
