This is a pre-order for the Robo-Tank conductivity circuit shipping around November 30, 2024, Save 20% by pre-ordering today!

This is a precise, fully isolated conductivity circuit constructed using high quality components and designed to work with Robo-Tank and reef-pi or any other microcontroller.

The circuit utilizes the newest isolation technology (power and data) to prevent noise from entering the circuit through the microcontroller, power supply or your aquarium. A conductivity circuit is a sensitive device and it doesn't take much to cause interference, with isolation noise is blocked so you continue to get accurate readings. This also blocks interference from multiple probes in the same aquarium.

You can connect multiple circuits using only 4 pins (SCL/SDA, +5v and GND) There's an extra set of headers on PCB to daisy chain multiple circuits.

• Outputs Conductivity, TDS, Salinity and Specific Gravity (only conductivity for reef-pi)
• Fully Isolated power and data lines
• Calibration through app
• Manually Change and Save I2C Address to circuit
• Compatible with any brand and type of Conductivity probe with BNC connector
• 5v Operating Range
• I2C Communication - Default Address 99 (0x64)
• 30mm x 70mm PCB size

Add an optional 3D printed case for the circuit, optionally you can print one yourself by downloading the STL files from the homepage
