About monitoring here
A logger in Hodeidah is arranged case by case, whether for food and beverage or pharmaceutical sites. Hodeidah is a port city on the Red Sea coast of western Yemen, the main town of the Tihama plain, and a temperature data logger here serves a harbour town of fish, food and medicine stores in very hot, humid air. Fishing boats land their catch each day, markets and wholesalers sell food and household goods to a wide hinterland, and the harbour area is crowded with sheds, offices and small warehouses. Hospitals and clinics serve the city and the villages of the plain, and a seafront promenade follows the shore. Heat and moisture stay high all year, and nights offer little relief. The loggers store their readings on their own batteries when a network is absent. We take every Hodeidah request case by case.
Temperatures stay high through the year, the air is full of moisture and salt, and the plain is flat, so stores and vehicles have almost no cool hours to recover and condensation is a daily event. Power cuts are common enough to plan for, and many businesses rely on generators or ice, which makes a record of when a room warmed especially valuable. Docks, markets and the seafront draw crowds all day, so doors open constantly and cold air escapes.
Areas
Boats land fish at the shore each morning and ice plants and cold rooms keep it for the market in the hottest part of the day.
Importers and wholesalers keep rice, flour, oil and drinks in sheds and warehouses where the roof sets the room temperature.
Hospitals, clinics and pharmacies hold vaccines, insulin and medicines in refrigerators that work hard in the heat and must survive outages of power.
Shops sell dairy products, drinks, sweets and household goods from small rooms with simple coolers, opened constantly through the day.
Industries
Hodeidah fish traders, importers and grocers hold goods that spoil quickly in heat, and a record from each cold store shows when a chiller began to fail.
Medicine distributors and pharmacies in Hodeidah keep stock to stated ranges, and a dated log shows how a room behaved through the hottest weeks and any power cut.
Goods that wait in sheds and vehicles near the harbour meet heat and salt, and a logger placed in a consignment records what each lot went through.
Hodeidah hospitals hold vaccines and blood products for the plain, and a phone alert reaches the person on duty when a refrigerator warms in the night.

Why Prithvi
FAQ
A logger in the ice room or cold store records through the day and night, and a report for the dates of one lot can be exported in PDF, Excel or CSV form for a buyer. See how a Prithvi temperature data logger works.
Moist sea air condenses on cold surfaces and softens cartons, so a humidity trend beside the temperature shows how much damp each opening of a door brought in.
The logger keeps recording from its battery and stores the readings, so there is a record for the hours without power or signal, available once the site connects.
Write with the town, the rooms to watch and a contact on the enquiry form or WhatsApp. Supply to Yemen is weighed case by case, and we reply with what is workable.
