Environmental Monitoring for Pharmaceutical
Monitor cleanroom humidity, differential pressure, and temperature conditions in real time. Maintain continuous GMP compliance records across all controlled zones.
Where Things Break Down
A humidity excursion in a Grade B cleanroom triggers a deviation investigation
GMP requires documented environmental control in production areas. When humidity drifts outside specification, the deviation investigation alone can cost $15,000-$50,000 before any product impact is assessed.
Pressure differential drops between zones compromise containment
Controlled areas rely on pressure cascades to prevent cross-contamination. A pressure differential that drops below specification may not trigger an alarm on the BMS, but it creates a compliance gap that regulators will find.
Environmental monitoring records have gaps that regulators flag
Data logger downloads fail, calibration records go missing, and paper logs have illegible entries. Every gap in the environmental record is a potential audit finding that requires a corrective action.
What Sandhed Does Differently
Sandhed connects to Shelly H&T sensors for temperature and humidity, and accepts additional environmental data from Kepware gateways and the REST Telemetry API for metrics like air pressure and particulate counts. Every reading is mapped to the sensor's physical location on your 3D floor plan. You see multi-sensor overlays showing temperature, humidity, and other parameters as color-coded zones. Thresholds are set per sensor and per metric, so each cleanroom class or controlled area has its own acceptable ranges. When conditions drift, alerts are created with automatic severity calculation and routed to the right team via email. All readings are stored in time-series format for compliance documentation.
Multi-Sensor Environmental Overlays
View temperature, humidity, and additional environmental parameters as layered color-coded overlays on your 3D floor plan. Switch between metrics to see which zones are in range and which need attention.
Zone-Specific Threshold Configuration
Set independent high and low thresholds for each sensor and each metric. A cleanroom can have humidity limits of 30-65% while an adjacent storage area has different requirements. Each zone enforces its own rules.
Severity-Based Alert Routing
Small drifts generate warnings sent to facilities teams. Readings 20% or more beyond a threshold trigger critical alerts routed to quality management. Each team member controls which severity levels they receive.
Continuous Compliance Records
Every environmental reading stored with a timestamp in time-series format. Alert lifecycle data, including creation, acknowledgment, and resolution, provides a complete audit trail. Pull records for any zone over any time period.
Results You Can Measure
Common Questions
Sandhed monitors temperature and humidity directly through Shelly H&T Gen3 sensors. For additional parameters like air pressure, particulate counts, or differential pressure, you can connect through Kepware gateways (OPC UA, MQTT, Modbus TCP) or send data directly via the REST Telemetry API. All parameters are displayed on the same 3D floor plan with the same threshold alerting system.
Yes. Thresholds are configured per sensor, per metric. You can set ISO Class 7 cleanroom requirements in one area, cold storage limits in another, and ambient warehouse conditions in a third. Each zone enforces its own high and low thresholds independently.
Every sensor reading is stored in TimescaleDB with a precise timestamp. The alert system records when thresholds were breached, when alerts were acknowledged (and by whom), and when conditions returned to normal. This creates a continuous, timestamped record that can be pulled for any zone over any time period without manual assembly.
When a sensor reading returns to within the configured threshold range, Sandhed automatically resolves the active alert and records the resolution timestamp. This auto-resolution ensures your alert list reflects current conditions without requiring manual cleanup, and the full excursion duration is documented.
Yes. Alert email subscriptions are configured per user with individual severity toggles. A facilities manager can receive all severity levels, while a QA director only receives critical alerts. Each user controls their notification preferences through the admin panel.

Temperature Monitoring
A 2-degree drift in a freezer or pasteurizer can destroy product, trigger recalls, and halt production. Sandhed maps live temperature data from Shelly sensors onto your 3D floor plan so you see every cold chain risk the moment it starts.
