About monitoring here
A logger in Diu is most often placed at food and beverage and logistics and warehousing sites around Fishing harbour and ice plants and Beach hotels and guesthouses. Diu is a small island off the southern tip of the Saurashtra coast, joined to the mainland by bridges, and a temperature data logger here serves a place of fishing, tourism and quiet trade. An old Portuguese fort stands at the eastern end, a large church and the lanes of the old town lie beside it, and beaches such as Nagoa and Ghoghla draw visitors for much of the year. Fishing boats land their catch at the western end of the island, ice plants and cold rooms hold it, and a small industrial estate at Bucharwada holds workshops and light industry. Hotels, guesthouses and bars cook and chill for holiday crowds. Prithvi supplies WiFi loggers for kitchens and rooms with a network and GSM loggers for boats, lorries and stores.
The island is hot and humid with salt in every breeze, the monsoon is heavy and cyclones can pass along the coast, so equipment corrodes quickly and power cuts after a storm test every cold room.
Areas
Boats land fish at the island's harbour, where ice plants, cold rooms and packers hold the catch before it travels to markets on the mainland in warm, salty air.
Hotels and resorts near Nagoa and Ghoghla beaches run walk-in coolers, bar fridges and kitchens that are loaded hardest in the holiday months and sit quiet in the monsoon.
Shops, bakeries and eating houses in the old lanes keep chillers and stock rooms in thick-walled buildings, where space for refrigeration was found long after the walls were built.
A small estate holds workshops, packaging and light industry with storage sheds that heat quickly under their roofs.
Industries
Fish packers, hotel kitchens and bakeries run ice rooms and coolers that must hold their limits in coastal heat, and a record from each unit shows exactly when one began to fail.
Fish and supplies cross the bridges by lorry, and a GSM logger placed in the load records the temperature through the whole crossing and the road beyond.
A small hospital and the clinics on the island hold vaccines and medicines, and an alert on a phone means a failing refrigerator is noticed in a stormy night.
Workshops and packaging firms in the estate keep paints, resins and cleaning chemicals with printed storage limits, and an alert from a hot shed lets the storekeeper act.

Why Prithvi
FAQ
Yes. The engineer or manager on duty is alerted by phone and email as soon as a cooler crosses its limit, and a second person can be set to take over if there is no reply. See how a Prithvi temperature data logger works.
A logger in a closed kitchen keeps recording, so a rise in temperature or a lost mains supply is reported even when nobody visits, and the record from the quiet months shows whether the unit held.
A logger in the ice room, the cold room and the lorry records the whole chain, and a report for the dates of one lot can be exported for the buyer.
