Pharma cold chain temperature monitoring
with IoT sensors
Wireless IoT sensors that monitor temperature and humidity 24/7 in pharma warehouses, vaccine cold rooms, blood banks, and hospital pharmacies. Instant alerts when readings drift out of range. Audit-ready reports generated automatically for WHO-GDP and CDSCO Schedule M compliance.
What you are dealing with today.
Manual temperature logs miss excursions between readings
Staff record fridge temperatures twice a day on paper. Between readings, a compressor failure or power cut can push temperatures out of range for hours. By the time the next manual reading happens, vaccines or biologics may already be compromised.
Paper logs fail audits and cannot be verified
WHO-GDP and CDSCO Schedule M require continuous, verifiable temperature records. Paper logs are easy to backfill and impossible to verify. Auditors flag manual records as unreliable, risking licence suspension.
Spoiled inventory is discovered too late
A single fridge failure overnight can destroy lakhs worth of vaccines, insulin, or blood products. Without real-time alerts, the loss is discovered only when staff arrive the next morning.
From setup to results.
Install wireless sensors in cold storage zones
Place compact wireless sensors inside pharmaceutical fridges, walk-in cold rooms, blood bank refrigerators, and ambient storage areas. Sensors connect via WiFi or 4G to the cloud dashboard. No wiring required.

Sensors report readings every 60 seconds
Temperature and humidity data is transmitted to the cloud dashboard continuously. Live readings, trend graphs, and historical data are available for every sensor from any browser or mobile device.
Sensor Data
Updated 30s agoInstant alerts when readings drift out of range
The moment a reading crosses your configured threshold, alerts are sent via SMS, WhatsApp, email, and voice call. Staff can move inventory to a backup unit before damage occurs. Escalation rules ensure no alert goes unacknowledged.
Alert Configuration
Add Rule| Rule | Threshold | Channel | Status |
|---|---|---|---|
| High temp warning | > 7°C for 5min | SMS + Email | Active |
| Critical temp | > 8°C for 2min | SMS + Call + Siren | Active |
| Low temp warning | < 1°C for 5min | SMS + Email | Active |
| Door open | > 3 minutes | SMS | Active |

Battery backup and offline logging
Built-in battery keeps the sensor running for up to 72 hours during power outages. Data is logged locally on the sensor and syncs automatically when connectivity is restored. No data gaps.
Power Status
Tamper-evident sensor design
Tamper alerts notify administrators if a sensor is moved, disconnected, or opened. Prevents staff from relocating sensors to favourable positions to mask temperature excursions.

What it looks like in practice.
Vaccine distribution centre, Ahmedabad
A regional vaccine distribution centre storing vaccines for government immunisation programmes was losing 8-12% of stock to temperature excursions. Manual temperature logs were recorded twice daily, missing overnight compressor failures and weekend power cuts. Two audit cycles flagged non-compliance with WHO-GDP cold chain requirements.
After deploying IoT temperature loggers across all cold rooms and refrigerators, cold chain compliance improved from below 88% to 97%. Stock wastage due to temperature excursions dropped to near zero. The next WHO-GDP audit was cleared with no observations.
"We used to find out about temperature problems the next morning when staff opened the cold room. By then, an entire batch could be compromised. Now we get an alert on our phones within a minute of any excursion. We have not lost a single batch to temperature failure since the system went live."Dr. Neha T., Quality Assurance Head, Vaccine Distribution Centre
