About monitoring here
Kollam is the old port city of southern Kerala on the shore of Ashtamudi Lake, and it is known above all for cashew: factories in and around the city shell, grade and pack the nuts that come in by sea and by road. Fishing boats land their catch at the Neendakara harbour, coir is spun and woven along the lake and canals, and clay and ceramic works at Kundara and the mineral-sand and titanium-pigment works at Chavara add heavier trades. The railway junction and the national highway link the city to Thiruvananthapuram and Kochi. A temperature data logger in Kollam therefore watches packed cashew in humid stores, seafood in ice rooms and cold stores, drums in the mineral works and medicines in hospital pharmacies. Prithvi supplies WiFi loggers for rooms and GSM loggers for vehicles and harbour stores.
The coast is warm and humid in every month, the monsoon is long and heavy, and salt in the air attacks metal and packaging, so humidity decides how packed cashew keeps while heat threatens the fish.
Areas
Factories around the city shell, dry and grade the nuts, and packing sheds hold finished cartons for export in air so damp that a sealed pack can still carry moisture.
Boats land fish at the harbours, and ice plants, cold stores and processors hold the catch before it is packed and sent inland or abroad in warm, salty air.
Ceramic works at Kundara and mineral-sand and pigment works at Chavara keep chemicals, bags and finished product in sheds that bake in the weeks before the rains.
Coir is spun, dyed and baled in workshops along the lake and canals, and bales of fibre and mats wait in sheds where damp can bring mould.
Industries
Cashew processors and seafood exporters hold goods that spoil in warm, damp air, and a record from each store and cold room shows an overseas buyer how a lot was kept before shipment.
Ceramic, pigment and mineral works keep bagged and drummed material with printed storage limits, and an alert from a baking shed lets the storekeeper act before the limit is crossed.
Carriers and godown operators move cashew, fish and coir out by road and rail, and a logger in the consignment records how long it stood in a siding or a vehicle.
Hospitals and a medical college serve the city and the districts around it, and alerts on a phone mean a failing refrigerator is noticed in a stormy night and not at the morning round.

Temperature + humidity
Single-channel WiFi temperature and humidity logger, internal or external sensor.
Nakshatra in Kollam: Temperature and humidity at one point suit a cashew packing shed or a coir store, where damp air reaching the cartons is the danger.

2 × temperature, or 2 × temperature + humidity (Pro)
Two-channel WiFi logger for temperature, or temperature and humidity, at two points.
Rajmudra in Kollam: Two channels at opposite ends of a fish cold room reveal whether the cold reaches the far wall or stops near the compressor.

Why Prithvi
FAQ
A humidity and temperature record from the packing shed can be exported by lot and date, so an exporter can answer a buyer's question about moisture or odour on arrival with the actual record.
Send the place, the unit and a contact through the enquiry form, WhatsApp or a call, and we confirm how a visit would be arranged for the harbours and the industrial areas around Kollam. See how a Prithvi temperature data logger works.
We keep loggers away from open doors and seaward walls where salt spray settles, and add a second probe at the far end of the room, so the record reflects the stored goods and not the corroding air by the door.
Every shed can be registered as its own site with its own alert contacts, so an owner of several sheds sees them together and can export one room's report on request.
