About monitoring here
Shimla is the capital of Himachal Pradesh, built along a ridge at the end of the road and the narrow-gauge railway from Kalka, and its storage serves government offices, a large medical college and hospital, hotels that fill in summer and winter, and the apple and fruit growers of the surrounding hills. Neighbourhoods such as Sanjauli, Dhalli and Chhota Shimla hold markets, clinics and guest houses on steep slopes where deliveries arrive by narrow road. A temperature data logger in Shimla therefore watches different risks than most cities: freezing in winter stores and vehicles, heat only in the odd warm spell, apples and other fruit held in cold and controlled-atmosphere stores, vaccines in hospital refrigerators and kitchens in hotels. Prithvi supplies WiFi loggers for rooms and GSM loggers for vehicles on the mountain road.
Summers are cool, the monsoon is heavy with landslides on the roads, and winters bring snow and temperatures that fall below freezing, so the danger to stored goods is as often cold as heat.
Areas
The state's medical college and its hospital, with clinics and pharmacies around them on the ridge, keep vaccines, blood components and medicines in many refrigerators serving the whole state.
Residential and market districts on the slopes hold clinics, shops, guest houses and small stores, where stock arrives by narrow road and freezing nights can reach unheated rooms.
Apple and other fruit from the surrounding hills are held in cold stores around the town before they go to the plains, and a warm spell shortens the keeping life of the whole lot.
Hotels, restaurants and bakeries serving visitors keep walk-in coolers and freezers that work hardest in the tourist seasons, in buildings with little space for equipment.
Industries
The medical college hospital and the clinics of the ridge keep vaccines and blood components in many refrigerators, and winter snow can cut both the power and the road for deliveries.
Fruit growers, hotel kitchens and bakeries hold stock that suffers from freezing as much as from warmth, and a record with both a high and a low limit shows when a store left its range.
Medicine wholesalers supplying hill chemists hold stock in stores that can chill below their printed limits in winter, and a low-limit alert warns the owner before a lot freezes.
Carriers on the mountain road carry goods that spend hours in cold or sun between the plains and the capital, and a logger in the load records the whole climb.

Why Prithvi
FAQ
We choose loggers and probes rated for the range, keep them away from doors and outer walls where the night cold bites, and set a low-limit alert next to the high one so a store that drops toward freezing is flagged.
Send the building, the neighbourhood and a contact. Narrow roads and one-way traffic can affect arrival times, so we agree a day and a meeting point with you in advance and keep the visit short.
A temperature record from the cold room can be exported by lot and date, so an owner can show a buyer how the fruit was held, and an alert on a rising reading reaches a phone while the stock can still be moved. See how a Prithvi temperature data logger works.
A logger stores readings on its battery and sends them when the signal returns, and where a building has no Wi-Fi we can use a SIM-based Vayu logger on the mobile network.
