NEO-1 is a sensor and a data logger that wirelessly monitors temperature, humidity, VPD, heat index, and dew points for up to 3+ years on battery power. The ideal solution for climate-sensitive environments — 24/7 monitoring, real-time alerts, logs, and reports.
-40°F to 158°F. ±0.2°C accuracy across the 0–90°C range.
0% to 100% relative humidity. ±3% typical accuracy.
Derived "feels-like" temperature combining air temp and RH.
Condensation-risk forecasting for HVAC and storage applications.
Vapor pressure deficit — critical for greenhouses and horticulture.
Low-energy radio with 328 ft (100 m) broadcasting range, 4 dBm transmit power.
Upgradable to iMatrix Massive Mesh for networks of hundreds or thousands of sensors.
Over-the-air firmware updates via the Micro Gateway — no physical handling required.

We recommend the iMatrix Micro Gateway to automatically scan, connect, and send NEO sensor data to the cloud for worldwide access (sold separately). For massive networks, upgrade to our proprietary mesh and deploy the Series-1 Gateway.
The reading cadence is adjustable in iMatrix Cloud. More frequent readings mean shorter battery life — the default balance targets 3+ years.
0 – 100% RH, with some accuracy loss as you approach 100%. For condensing environments pair with the Neo-1P external probe.

-40°C to 70°C (-40°F to 158°F). For in-core cryogenic or liquid immersion, see the Neo-1P probe variant.
