About monitoring here
A logger in Kotdwar is most often placed at pharmaceutical and food and beverage sites around Wholesale bazaar and hill-bound godowns and Railway terminus and goods sheds. Kotdwar is the foothill town on the Khoh river where the plain ends and the Garhwal hills begin, and a temperature data logger here serves a trading gateway rather than a factory city. The railway line from the plains ends here, and goods for the hill markets of Pauri Garhwal and the army station beyond are unloaded, stored and reloaded on mountain lorries. Wholesalers of food, medicines, hardware and general goods supply shops in the hills, and a small industrial estate holds light engineering and food units. Pilgrims visit the Siddhbali temple, and a hospital and clinics serve the town and the hill villages. Prithvi supplies WiFi loggers for shops and stores with a network and GSM loggers for hill-bound lorries and stores beyond a router.
The foothills are hot and humid in summer, the monsoon is very heavy and can close hill roads, and winter nights are cold, so goods may wait for days in damp air and then climb into cold mountain weather.
Areas
Traders in the main bazaar stock food, medicines and general goods for shops in the hills, in godowns where stock waits for a lorry and damp collects in the rainy weeks.
Wagons arrive from the plains and goods are transferred to road transport, with parcels and bulk cargo waiting on the platform and in sheds between modes.
Light engineering, food and packaging firms on a small estate keep stores of materials and finished goods in sheds that heat under metal roofs.
A hospital, clinics and pharmacies serve the town and the hill villages, with vaccine fridges and medicine stores that must survive power cuts in storms.
Industries
Medicine wholesalers send consignments up winding roads to hill pharmacies, and a logger placed with the pack records the whole range of heat and cold it met on the journey.
Wholesalers of dairy, packed food and sweets supply hill shops that are hours away by road, and a reading from each chiller shows when a unit failed during a storm outage.
The hospital and clinics hold vaccines and medicines for patients who travel long distances, and an alert on a phone means a failing refrigerator is found in the night.
Carriers load at the terminus for hill towns, and landslides can hold a lorry for days, so a logger in the load records how long the goods waited and in what conditions.

Why Prithvi
FAQ
Yes. A GSM logger placed with the goods records readings along the journey and through any halt, and the owner can export the record for the buyer. See how a Prithvi temperature data logger works.
The logger keeps recording on its own memory and battery, and sends the stored readings when the signal returns, so the record has no gap.
Yes. A single-point logger with an alert to a phone is enough for one medicine fridge or chiller, and further points can be added to the same account later.
