Rack-level and room-level temperature and humidity tracking. ASHRAE-range alerts before thermal events escalate into hardware failure or emergency shutdowns. The cheap insurance policy every small colo and enterprise IT team should have already bought.
ASHRAE TC 9.9 recommends most IT equipment operate in a temperature range of 18–27°C (64.4–80.6°F) and humidity of 40–60% RH. Allowable ranges are wider (15–32°C / 20–80% RH depending on class), but staying in the recommended range extends equipment life and prevents thermal runaway.
Building management systems (BMS) usually read temperature at the CRAC return air — ~15 feet off the floor at the ceiling. That number looks fine while a single rack at the end of a hot aisle is pushing 35°C and throttling CPUs. Deploy sensors at rack-top and rack-bottom within critical racks, and you catch hot spots hours before a BMS alert.
Too dry: static electricity risk. Too humid: condensation on cool metal surfaces. iMatrix NEO-1D tracks both ambient temperature and humidity with configurable alert bands. For facilities without DCIM platforms, iMatrix Cloud is the monitoring layer.
Small colo (one room, 30–60 sensors): single Micro Gateway, Wi-Fi backhaul. Mid-size data center (5,000–20,000 sq ft, hundreds of sensors): Series-1 Mesh gateways distributed through the hot aisles. Enterprise-grade deployments can integrate with existing DCIM via the iMatrix Cloud API.
