Monitor hydroponic nutrient levels or salinity in pools
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.
All boards have a conformal coating to help protect against moisture, corrosion, and short circuits.
Any 2-electrode probe with a BNC connector and a cell constant of 1K can be attached to the device. EC probes are specified by their cell constant (K).
A probe with a cell constant of 1K is appropriate for hydroponics and saltwater pools.
When different probes are connected to the same controlling device, they can cause interference. The environment also causes interference due to ground-loops or other electrical noise like pumps. Electrically isolating the probe from the controlling device can help to prevent it.
All μFire probe interfaces come with electrical isolation hardware which provides a stable, isolated power supply and I2C bus between the interface and your controlling device.
