Thiruvananthapuram · Kerala


About monitoring here
Thiruvananthapuram is Kerala's capital, spread over low hills at the southern end of the state, and its storage is shaped by government, science and health rather than by heavy industry. The technology park at Kazhakoottam holds server rooms and laboratories, a medical college hospital, a regional cancer centre and a medical-technology institute keep large blood banks and pharmacies, and a space research centre and a biotechnology centre work on the coast and in the north of the city. The international seaport at Vizhinjam adds a cargo side that is new to the district. A temperature data logger in Thiruvananthapuram therefore sits as often in a laboratory freezer or a hospital refrigerator as in a cold room for fish. Prithvi supplies WiFi loggers for indoor rooms and GSM loggers for vehicles and coastal stores, and alerts follow a person to a phone.
The air stays warm and humid for most of the year, two monsoons bring long spells of rain and the sea breeze carries salt inland, so contacts corrode, condensation forms on cold surfaces and storms interrupt the power.
Areas
The large technology park on the northern side holds server rooms, test laboratories and hardware stores in tall buildings, where cooling is shared and run by facilities teams.
A government medical college hospital, a regional cancer centre and a medical-technology institute keep blood components, vaccines, reagents and radiopharmaceuticals in refrigerators and freezers on every floor.
The deep-water port and the landing centres along the southern coast handle cargo and fresh catch, with stores and ice rooms that stand in sun and salt air.
Small industrial estates on the city's edge hold food, packaging, electrical and engineering units, with stores of mixed age and size beside the production areas.
Industries
Large government and private hospitals keep blood components, vaccines and pharmacy stock in refrigerators across many wards, and a phone alert from a failing unit reaches the duty technician through a stormy night.
Research institutes and testing laboratories hold reagents, samples and cultures in freezers and incubators, and a logged record shows a supervisor or a funder that conditions held through monsoon power cuts.
Server rooms in the technology park run to narrow temperature and humidity bands, and an alert on a failing cooling unit reaches the engineer before the equipment is at risk.
Fish traders, hotel kitchens and food makers rely on ice rooms and walk-in coolers in warm air, and a door left open overnight should raise an alarm before the stock is lost.
Recommended products
A starting point for the sites above. Our team will help you choose.

4 × temperature, or 4 × temperature + humidity (Pro)
Four-channel WiFi logger for multi-point temperature or temperature and humidity.
Dhruva in Thiruvananthapuram: Four channels let one logger follow several refrigerators in a hospital pharmacy or a laboratory corridor and report each unit on its own line.

Temperature + humidity
Single-channel WiFi temperature and humidity logger, internal or external sensor.
Nakshatra in Thiruvananthapuram: Temperature and humidity at one point suit a server room or a reagent cabinet, where damp monsoon air is the risk worth catching.

Temperature + humidity
SIM-based GSM logger for sites and vehicles without Wi-Fi.
Vayu in Thiruvananthapuram: A SIM-based GSM logger travels with fish or medicines in a vehicle, or reports from a landing centre without Wi-Fi, which suits goods moving along the coast.
These services are delivered by our parent lab, VEGA Calibrations.Ask us to plan them for your Thiruvananthapuram site alongside your loggers.
Process
Tell us what you store, where, and how many points need watching.
We look at the layout and conditions, by call or on a site visit, and recommend the right loggers.
Loggers are supplied and installed, then connected to your dashboard and alert recipients.
We stay available for alert rules, user access and calibration planning as your sites change.
Why Prithvi
FAQ
A hospital group can set up each ward, pharmacy or laboratory as its own named location with separate alert contacts, then view every building in a single list when an inspector asks for records.
A logger carries on recording from its own battery, uploads the stored readings once the network returns, and can warn the person in charge that the supply was lost.
We agree positions with the facilities team on a short visit, placing loggers at rack height near the cold-aisle intake and the hot-aisle return, and nothing is wired into the building's own systems.
Send the place, the store and a contact through the enquiry form, WhatsApp or a call, and we confirm how a visit would be arranged for Vizhinjam and the coastal centres around the city. See how a Prithvi temperature data logger works.
