Monitor hydroponic nutrient levels or salinity.
An I2C sensor device, an optional DS18B20 waterproof temperature sensor, and a two-electrode conductivity probe. It measures the conductivity of a solution and converts it into Siemens (S) total dissolved solids and salinity. The firmware allows for accurate single-point calibration with temperature compensation.
The board uses the Qwiic Connect System for easy wiring. an easy-to-use, polarized, push-to-fit connector. No more mistaken connections or soldering header pins. All μFire devices use it for quick, easy, and permanent connections in an enclosure. But there is a through-hole header available if you don’t want to use it. Make sure you pick up some wires before 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.
