About monitoring here
Chennai is a port city whose industry fans out inland: engineering and electronics estates on the north-western side, large manufacturing parks to the south-west along the highways, and the container yards and warehouses that sit between the factories and the sea. A temperature data logger in Chennai has to cope with salty, humid air as much as with heat, and with goods that spend days between a plant and a ship. Pharmaceutical, electronics, automotive component and food firms all keep stock here that is sensitive to both, and many of them export, so customers abroad ask for the record of how a consignment was held. Wireless loggers with alerts to phones and email, and a dated log that can be exported by lot, give a plant and its forwarder one shared account.
The coast keeps heat and humidity high for most of the year and the north-east monsoon adds heavy rain late in it, so stores face sweating cartons and corroding contacts as well as warm air, and storms can cut power for long periods.
Areas
A large industrial estate in the north-west with engineering, electronics and small manufacturing units on compact plots, many of them supplying the larger plants further out.
A manufacturing hub to the south-west where electronics and automotive plants and their suppliers stand on large plots across a wide park.
An industrial park further along the south-western corridor with automotive, electronics and warehousing units that move goods toward the ports.
Industries
Pharmaceutical makers and distributors hold ingredients and finished packs in rooms with stated limits, and export customers expect a log that shows the room stayed in range through the humid months.
Electronics and component plants keep boards, connectors and finished sets in stores where salty air makes damp a quiet cause of failures, so humidity is watched alongside temperature.
Food processors and seafood exporters hold chilled and frozen stock in chambers that must stay in range through a long power cut during a storm.
Container freight stations and port-side warehouses hold goods that wait on a vessel's schedule, and a record for each bay shows how long a lot stood in coastal heat.

Temperature + humidity
Single-channel WiFi temperature and humidity logger, internal or external sensor.
Nakshatra in Chennai: Reads relative humidity together with temperature, which matters most in stores where sea air carries moisture through every door.

16 × temperature, or 16 × temperature + humidity (Pro)
Sixteen-channel WiFi logger for large facilities.
Virat in Chennai: Sixteen channels cover a large export warehouse across racks, dock doors and floor positions, so one device reports on a hall that would otherwise need many.

Temperature + humidity
SIM-based GSM logger for sites and vehicles without Wi-Fi.
Vayu in Chennai: A GSM logger with an external probe keeps reporting from a container or a yard where there is no building Wi-Fi, so a consignment's journey to the port is on record.
These services are delivered by our parent lab, VEGA Calibrations.Ask us to plan them for your Chennai 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
We plan them as separate days by direction, since Ambattur lies on the north-western side and the other two on the south-western corridor. Send the plants, the stores and the contacts and we propose an order.
Loggers carry on recording on their batteries, send stored readings when the network returns and GSM versions can still report if a building's Wi-Fi is down. Alerts for a lost mains supply go to the named people. See how a Prithvi temperature data logger works.
Journey and storage reports can be exported as PDF, Excel or CSV for each lot, so the file that travels with an export shipment shows the conditions it was held in before the port.
VEGA Calibrations, our parent company, calibrates loggers and probes and carries out temperature mapping, and the work can be scheduled with the visit so that placement and certificates are settled together.
