Monitor hydroponic nutrient levels or salinity in pools and soil.
An I2C sensor device, an optional DS18B20 waterproof temperature sensor, and a two-electrode EC probe. It measures the conductivity of a solution and converts it into Siemens (S). From that value, it derives total dissolved solids and salinity. The firmware on the device provides two calibration options, single or dual point which can be used simultaneously. Temperature compensation is also provided in the firmware.
The board uses the Qwiic connection system for easy wiring. No more mixing up pins or soldering header pins (but there is a through-hole header available if you don’t want to use it). Make sure you pick up some cables when you checkout.
Any 2-electrode probe can be attached to the device. EC probes are specified by their cell constant (K).
A probe with a K constant of:
The board can be purchased by itself, conductivity probes are also available separately. Buy the board and a probe and get the I2C Sensor Isolator board for 10% off. The discount will be automatically applied.
