Tentacle Mini

What's the Tentacle Mini?

An Arduino shield to host and individually isolate up to 2 sensor circuits from Atlas Scientific to measure PH, Dissolved Oxygen, Electric Conductivity (E.C.) and Oxidation-Reduction Potential (ORP), RTD (Temperature).

  • 2 channels
  • 3.3V and 5V compatible
  • I2C only

Individually isolated measurement circuits and communication lines prevent noise and ground loops for precise measurements.
