About monitoring here
Ahmedabad is the commercial centre of Gujarat, and its factories sit in a ring of planned estates around the Sabarmati plain instead of in one district. Pharmaceutical makers, chemical and dye units, food and dairy processors and engineering firms each have their own cluster, and the city's own warehouses and hospitals sit between them. A temperature data logger in Ahmedabad works against a hard fact of the climate: summers are very hot and dry, and a closed shed or a vehicle bay can climb far above the outside air by the afternoon. Alerts that reach a phone, and a log that shows when and for how long a room left its limits, give a quality head something firmer than a morning walk-round.
Very hot, dry summers heat sheds and loading bays well past the outside temperature, while winter nights are mild, so the swing between day and night is large and a room's real behaviour shows only in a continuous record.
Areas
An older estate on the northern side of the city, with engineering, chemical, plastics and packaging units that grew up alongside the surrounding neighbourhoods.
A south-eastern estate long associated with chemical, dye and pharmaceutical intermediate units, many of them on compact plots.
An estate on the western highway where pharmaceutical manufacturers and logistics firms sit within a short distance of each other.
A newer industrial district beyond the city's western ring road, with automotive, electronics, food and consumer-goods plants on large plots.
An estate to the south-west of the city, where food, chemical and engineering units use wider plots than the older estates allow.
Industries
Pharmaceutical manufacturers keep ingredients and finished goods in stores with printed limits, and in an Ahmedabad summer an air-conditioning fault is noticed on a log long before it is noticed on a shelf.
Dairy and food processors depend on chillers and cold rooms that work hardest in the dry heat, and an alert that escalates to a second and third person covers a failure that starts at night.
Chemical and dye units hold raw materials and drums in sheds where the afternoon heat is the main risk, so a high-temperature alert is as important as a low one.
Third-party warehouses and transport yards on the highways around the city hold goods briefly between plants and the road, and a dock-door reading shows how long a load stood in the sun.
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 Ahmedabad: Four channels watch a dairy or food cold room from floor to top rack and door, so a hot corner cannot hide behind the stock.

2 × temperature, or 2 × temperature + humidity (Pro)
Two-channel WiFi logger for temperature, or temperature and humidity, at two points.
Rajmudra in Ahmedabad: Two channels suit a chemical drum store or a stability room, with one probe in the hottest corner and one near the door.

16 × temperature, or 16 × temperature + humidity (Pro)
Sixteen-channel WiFi logger for large facilities.
Virat in Ahmedabad: Sixteen channels cover a large highway warehouse or a bulk pharmaceutical store, where heat builds unevenly under a metal roof.

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
Send the estate, the plot and the rooms you want looked at through the enquiry form, WhatsApp or a call, and we agree a day with the person who controls entry. Many estates ask for a gate pass in advance, so mention it when you write.
Internal sensors read from minus 30 to plus 70 degrees Celsius, and external probes extend that range far beyond it, so a probe can sit in a hot process area while the logger stays outside it in the cooler corridor. See how a Prithvi temperature data logger works.
Calibration, temperature mapping and validation support are carried out by VEGA Calibrations, our parent company. Send the instrument list and the rooms to be mapped, and we plan the work with you.
The alert moves up to a second and then a third recipient, and each acknowledgement can record the cause and the action taken, so the log shows what was done as well as what went wrong.
