Description

Tentacle is an Arduino shield to host up to 4 sensor circuits from Atlas Scientific to measure PH, Dissolved Oxygen, Electric Conductivity (E.C.) and Oxidation-Reduction Potential (ORP) and temperature (RTD). The sensor circuits are not included. Works with current and all previous versions of these Atlas Scientific sensor circuits: PH, EC, DO, ORP, RTD

Easy Setup

Use the setup sketch to easily set up your circuits interactively. It even comes with circuit auto-detection!

Compatibility

The Tentacle shield is COMPATIBLE with all 5V-tolerant Arduinos (Uno, Mega, Yun, & many more). However, the Tentacle shield is NOT COMPATIBLE with Arduinos that can’t tolerate 5V on their I/O pins (Zero, Due, etc). If you need 3.3V compatibility, the Tentacle Mini is for you.

  • stack 2 shields to get 8 isolated sensor channels
  • I2C and UART compatible

Isolation

Individually isolated measurement circuits and communication lines prevent noise and ground loops for precise measurements even in closed-loop systems. Read our blog post Atlas circuit isolation, noise & crosstalk tests for more details on the isolation of sensor circuits.

Mix and match legacy and new EZOTM sensor circuits

Compatible with all versions of sensor circuits by Atlas Scientific. Freely combine different types of sensors. For example use 4x PH or 2x PH and 2x E.C. or any combination of PH, dissolved oxygen, E.C., ORP, temperature that fits your needs.

With the on-board serial multiplexer you can use up to 4 serial sensor circuits (or EZOTM in serial mode) per shield using just 4 pins of your Arduino. Stack two tentacles to get 8 serial channels.

Arduino-style simplicity

Extra long pin headers to stack multiple tentacle (or other) shields on your Arduino hassle-free. On-Board reset-button to reset your Arduino without removing shields. Includes a mounting kit with plastic standoffs.

    Eric Burger

    Great Shield! Very easy to use and to customize to a project. Also, the whitebox example code is really good. I wouldn’t recommend getting any of the sensors without also getting this shield. The readings from my pH sensor were useless until I added the tentacle shield.
