A stackable arduino shield to host and individually isolate up to 2 EZO circuits from Atlas Scientific to measure PH, Dissolved Oxygen, Electric Conductivity (E.C.), Oxidation-Reduction Potential (ORP) and temperature (RTD).

Please select:

  • kit: The Arduino pin headers are included, but not soldered. You can solder the included headers or use your custom connectors
  • assembled: Tentacle ships fully assembled and ready to use

Description

A fast and easy way to read multiple sensors from an Arduino. The Tentacle Shield eliminates the need for wiring, multiplexing and electrical isolation. Because it’s an Arduino Shield, it simply plugs into most Arduino compatible boards. No wiring, no bread boards.

Built in electrical isolation means that sensors won’t interfere with each other and most outside electrical noise that can interfere with readings is reduced.

  •  3.3V and 5V compatible
  • stack up to 3 shields to get 6 isolated sensor channels
  • I2C ONLY
  • The sensor circuits are not included.

Easy Setup

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

Compatibility

  • The Tentacle Mini is COMPATIBLE with all Arduinos with the R3 pin layout. The Mini is 3.3V and 5V compatible.
  • The Tentacle Mini is compatible with all EZOTM type circuits from Atlas Scientific that support I2C mode. The Mini will not work with older sensor circuits that support UART only. If you still want to use UART circuits, use the 4-channel Tentacle Shield.

    100% professional grade board. If you are using Atlas Scientific EZO circuits this board is a must have. It completely isolates each probe allowing
    you to use multiple probes in the same solution without interference as well as providing electrical noise isolation. I live in Canada and ordered my
    mini on a Monday and it arrived at my door on Friday …. awesome. Excellent product, service and company. Hats off to Whitebox Labs and their
    techs.
