Lab Monitoring & Sensor Logging

Continuous per-bench monitoring with calibration tracking and threshold alerts — without a SCADA budget. Built for research labs, biotech R&D, food science, and pharma storage.

The Problem

Enterprise SCADA is overkill — but spreadsheets miss events

Lab-scale buyers do not have a SCADA budget but cannot trust a weekly Excel rollup. There is a wide gap between $0 and a $20k integrator quote.

Manual sample-rate adjustments

Some experiments need 1-minute logging; others log for weeks at hour intervals. Switching between protocols on legacy data loggers is friction.

No cross-bench visibility

Each bench, fridge, freezer, or incubator gets its own data logger with its own export workflow. Side-by-side comparison is manual.

Calibration drift goes unnoticed

Sensors drift over time. Without tracked calibration history, today’s reading and last quarter’s reading are not actually comparable.

How LoopString Solves It

Multi-bench live dashboard

See temperature, humidity, CO₂, pressure, and any analog/digital input from every Pi-equipped bench on one screen.

Sample-rate flexibility per signal

Configure per-signal sample intervals — from 1 Hz for short experiments down to per-minute for long ambient logging. PID loops on the edge.

Threshold + anomaly alerts

Freezer warming over -20 °C, incubator drifting, autoclave failure, gas-cabinet alarm — every channel can have its own threshold and recipient list.

Calibration + audit trail

Track per-sensor calibration parameters and history. Every reading is timestamped and queryable. Export sensor history per device for review.

Used by these lab operations

University research labs

Per-bench monitoring with shared dashboards across rotating grad students and staff.

Biotech R&D

Per-incubator and per-fridge environmental logging that survives a -80 °C failure.

Food science / sensory labs

Temperature + humidity + door-event logs across sample storage and prep rooms.

Pharma stability + storage

Continuous storage-condition logs for stability studies (per-shelf sensors, audit-grade history).

Cleanroom + climate-controlled production

Per-zone climate monitoring with deviation alerts for non-conformance reporting.

Independent contract testing labs

Per-customer-project zones, per-zone dashboards, exportable history for client reports.
