About monitoring here
Varanasi is one of the oldest living cities, spread along the Ganga, and its economy mixes pilgrimage, craft and a locomotive works. Pilgrims fill the lanes beside the ghats, hotels and kitchens feed them, and weavers in Madanpura and Lallapura produce Banarasi silk saris on looms in small rooms. The university campus runs a large hospital, the Ramnagar and Chandpur estates hold engineering and food units, and the Langra mango grows in the region. A temperature data logger in Varanasi might sit in a silk store, a hospital pharmacy or a guest-house kitchen. The air is hot and humid, the Ganga floods low land in the monsoon and winter fog is thick, so damp is as constant a threat as heat.
Summers are hot, the monsoon is humid and the Ganga rises over its lower banks, while winter brings thick fog, so silk, paper and food stock face damp for a large part of the year.
Areas
An industrial area across the river from the old city, with engineering, small manufacturing and food units on mid-sized plots and godowns near the bridge.
An industrial area on the western side with a mix of food, engineering and packaging units, where sheds are modest and storage is shared with production.
Weaving neighbourhoods near the old city, where silk yarn, brocade and finished saris are stored in small rooms that hold heat and damp in turn.
A large university campus and its teaching hospital serve patients from eastern Uttar Pradesh and beyond, with blood banks, pharmacies and laboratories.
The narrow lanes beside the river with guest houses, shops and kitchens, where fridges and storerooms sit in old buildings close to the water.
Industries
Silk and brocade are sensitive to damp, and weavers and traders keep yarn and finished saris in rooms where a humidity record shows when a cupboard needs drying.
A large teaching hospital and many private clinics run blood banks, vaccine fridges and pharmacies, with alarms for the duty staff through summer power cuts.
Guest houses, sweet makers and mango traders keep fridges and cool rooms through a humid season, and a probe in each gives the owner a record without a night-time visit.
Godowns beside the highways and the rail yards hold goods in transit between the plains and the east, and a reading at each bay shows how long a lot stood in damp heat.

Why Prithvi
FAQ
Yes. A small WiFi logger on a shelf, with alerts to the trader's phone, shows when a room turns damp, and a second can be added for another cupboard later.
Fix loggers well above the likely water level and keep probe cables out of drains. A GSM model keeps reporting if WiFi fails, so an alert still reaches a phone.
Yes. Send the estate, the type of room and a contact, and we plan visits by direction so that nearby sites are covered on the same day. See how a Prithvi temperature data logger works.
VEGA Calibrations, our parent company, calibrates loggers and probes and supports validation. Share the model and range, and we explain how it is arranged for the hospital.
