About monitoring here
Agra is a city of two economies. Millions of visitors come for the Taj Mahal and the fort, which keeps hotels on Fatehabad Road and kitchens across the city busy, while the older trades of footwear, leather and metal casting fill the estates at Foundry Nagar and Sikandra. The surrounding country grows potatoes, and many cold stores stand on the roads out of town. A temperature data logger in Agra might therefore sit in a hotel walk-in fridge, a potato cold store, a shoe factory's glue and chemical room or a sweet maker's kitchen, famous for petha. The city lies on the Yamuna and on the Delhi–Gwalior highway, and an expressway now links it to Lucknow. Summers are scorching, winters foggy and the monsoon humid.
Summers are scorching and dry, winter mornings are cold and foggy, and the humid monsoon follows, so cold stores work hard for most of the year and hotel kitchens meet heat inside as well as out.
Areas
The foundry and metal-casting estate, with furnaces, pattern shops and casting stores, where heat from the process adds to the summer sun in sheds and stockrooms.
An industrial belt on the Mathura side of the city with footwear, leather and engineering units, whose adhesive and chemical stores need steady storage.
The hotel strip near the Taj Mahal, with restaurants and kitchens running walk-in fridges, freezers and cold rooms for visitors through the tourist season.
Old market lanes where petha, sweets and namkeen are made and sold, in kitchens and shops that handle milk, sugar and fried goods in hot, tight rooms.
Large cold stores on the roads out of town that hold the potato harvest for months, where stable temperature and humidity decide how stock keeps.
Industries
Cold stores, sweet makers and hotel kitchens depend on chambers that cannot drift, and a record of every reading shows when a compressor began to struggle in the afternoon.
Footwear makers hold adhesives and solvents with storage limits, and an alert on heat gives the stores person a chance to act before drums are affected.
Warehouses on the highways hold leather goods, shoes and handicrafts for buyers elsewhere, and a reading at floor and roof level shows how damp or heat collects in cartons.
Hospitals serve residents and visitors alike and keep vaccine fridges and blood banks that need alarms to reach duty staff through summer power cuts.

Why Prithvi
FAQ
Several probes at different heights and chambers, with a humidity reading, show how evenly the store holds its range. Tell us the chamber layout and we suggest the points.
Yes. Each kitchen is a point on the dashboard, alerts go to the engineer who looks after it, and a manager can see all of them together and export a report for any period.
Yes. We plan visits by direction from the city, so Sikandra and Foundry Nagar can be covered on the same day. Send the room, the contact and the working hours. See how a Prithvi temperature data logger works.
