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.

5 Channels

Channel 1

A non-isolated channel for EZO circuits that do not need isolation – Like the EZO RTD and EZO Flow.

Channels 2 + 3

  • 2 individually isolated channels for EZO circuits like EZO pH, EZO DO, EZO ORP, EZO Conductivity.
  • channels can be switched off completely for low-power applications.

Channel 4 + 5

Data cable connectors for EZO devices like the EZO CO2, EZO RGB, EZO PRS, EZO PMP.

A non-isolated channel for EZO circuits that do not need isolation – Like the EZO RTD and EZO Flow.

Example Code

  • Coming soon  (Summer 2020)

Configuration

  • The isolated channels 2 + 3 can be switched off completely by pulling the respective pin LOW. This will switch off the isolator circuit and the EZO circuit to bring power consumption down to almost 0. The ENABLE pins can be patched to an Arduino digital pin.
  • The EZO 5-pin devices have an INT pin for interrupts or other I/O functions. The INT pins for channels 4 + 5 can be patched to an Arduino digital pin.

Compatibility

  • COMPATIBLE with all Arduinos with the R3 pin layout. The Mini is 3.3V and 5V compatible.
  • compatible with all EZOTM circuits from Atlas Scientific that support I2C mode.
  • compatible with all EZOTM devices with data cable from Atlas Scientific
