About monitoring here
Salem lies in a ring of hills in north-western Tamil Nadu and is known for stainless steel, sago and starch made from tapioca, and the mangoes of its orchards. A large steel plant stands on the edge of the city, magnesite and iron-ore workings lie in the hills, and the older trades are handloom and power-loom weaving, silk and the markets of Shevapet and Leigh Bazaar. Suramangalam and Ammapet hold small factories and textile units, while sago mills line the roads that lead to the farms. A temperature data logger in Salem therefore watches sacked starch in a damp monsoon, mangoes in ripening and cold rooms, textile stores and the vaccine refrigerators of a large government hospital. Prithvi supplies WiFi loggers for rooms and GSM loggers for vehicles, with alerts to phones and email.
The city sits in a basin of hills that holds the heat, so summers are hot and still, the monsoon brings damp that settles into sacked starch and cloth, and the nights are cooler than the days.
Areas
Mills on the roads to the tapioca farms hold sacked starch and sago in large godowns, where damp air in the rains can cause lumps, mould and a smell that buyers reject.
Small factories, workshops and textile units in these areas keep stores of yarn, packing material and engineering consumables in buildings of mixed age and size.
Crowded trading lanes hold cloth, groceries, mangoes and medicines in godowns behind shops, where a single building may hold stock for several traders.
A large government hospital and a medical college, with private hospitals around them, keep vaccines, blood components and medicines in many refrigerators serving several districts.
Industries
Sago and starch mills and mango traders hold produce that suffers in heat and damp, and a humidity and temperature record shows an owner when to ventilate, move or sell a lot.
Weavers and cloth merchants keep yarn and finished rolls in rooms that turn damp in the rains, and a humidity record shows a buyer how the stock was held before it was packed.
Steel-related suppliers and engineering units hold coatings, acids and lubricants with printed storage limits, and an alert from a heated store lets the storekeeper act before material is spoiled.
The government hospital and private hospitals keep blood components and vaccines in many refrigerators, and alerts to a phone mean a unit that fails overnight is not found at the morning round.

Why Prithvi
FAQ
A humidity record from the godown can be exported by lot and date, so a miller can answer a buyer's question about how the starch was kept through the rains before dispatch.
Send the area, the unit and a contact through the enquiry form, WhatsApp or a call, and we confirm how a visit would be arranged for the pockets around Salem. See how a Prithvi temperature data logger works.
Loggers are small and battery powered, so they hang from a shelf or stand on a rack without cabling, and we agree positions with the trader who holds the keys.
Each place becomes a site with its own alert recipients, so an owner can open both on one dashboard and see which one needs a call to the manager.
