Warehouse Heat Mapping: Inventory Risk Control in a German Logistics Center

An acceptable average temperature doesn't mean every rack is safe — distributed S05-TH sensors and a live heat map let this German logistics center see temperature and humidity differences across rack levels and zones on one screen.

Project Profile

• Region: Germany
• Category: Logistics
• Products: S05-TH

Reference Impact

• Rack-Level — Heat-map visualization by rack tier (Multi-zone warehouse)
• Hot-Spot Detection — Localized temperature gaps on high racks (Fewer blind spots)
• Est. 20% — Faster response to hot spots (Estimated improvement)

Case Snapshot

An acceptable warehouse average doesn't mean every storage position is safe — that was the realization at a large logistics center in Germany reviewing its inventory risk. Rack height, storage zones, airflow patterns, and product categories can all create localized temperature and humidity differences, yet a handful of monitoring points rarely catches a hot spot on a high rack in time. Distributed S05-TH wireless sensors, placed by rack height and zone, paired with a live heat map now surface those anomalies earlier.

Problem

A few monitoring points miss the corners

Large logistics facilities often store general goods, temperature-sensitive inventory, and stock with different turnover profiles side by side. Relying on a handful of fixed monitoring points mostly returns localized or averaged data, which may not reflect actual conditions on high racks, in corners, in airflow dead zones, or in specific storage areas.

When a rack's temperature has quietly run high for hours, the first signal is often a complaint or a return, not a monitoring log — and there's rarely data on hand to point to which tier or zone was responsible. A passing average doesn't mean every rack, every corner, is equally safe.

Solution

Sensors placed by rack tier and zone

The team deployed S05-TH wireless temperature and humidity sensors across multiple warehouse zones, distributed according to rack height, section, and product storage characteristics. Sensors continuously reported readings, which the platform compiled into a dynamic, zone-based heat map.

Managers could compare conditions across zones from a single visual interface, and when any zone crossed a preset threshold, the system raised an alert so staff could investigate before inventory risk escalated.

Value

From one average to every rack's own picture

Managers can compare temperature and humidity across racks and zones on one heat map, instead of guessing which zone might be a problem or depending on a handful of monitoring points and after-the-fact checks. Localized heat, airflow dead zones, and storage-placement issues get flagged earlier.

That strengthens quality control and compliance records for sensitive inventory. After a heat-map walkthrough, a manager's first move isn't guessing which zone to check — it's opening the one rack tier that's actually running hot, with the response and the record keeping pace instead of waiting for the next spot check.

Next Step

Provide the rack layout, storage heights, and current measurement points to identify where average readings may be masking local hot spots before defining a pilot zone.
