Enhance Your Monitoring

We recommend the iMatrix Micro Gateway to automatically scan, connect and send your NEO sensor data to the Cloud for word-wide access ( sold separately).

iMatrix sensors are upgradable to our proprietary mesh solution supporting massive networks. For massive networks we recommend the Series-1 Gateway (sold separately).

  • What levels of humidity can the NEO-1D detect?

    This sensor can read relative humidity from as low as 0% up to nearly 100%, although accuracy will lower once the humidity approaches 100%.


  • How do I view data from my NEO-1D?

    The NEO-1D comes with a display that allows you to check readings on the sensor itself. Once your sensor is connected to your account, you can also view your data in the iMatrix Cloud portal, or the iMatrix mobile app.

  • Is it safe to place my sensor in liquids?

    The NEO-1D comes with a casing to protect it from high humidity, however, this casing does not prevent damage if the sensor is fully submerged. Only sensors with a probe extension can be submerged.
