About monitoring here
A logger in Seiyun is arranged case by case, whether for food and beverage or hospital and blood bank sites. Seiyun is a major town of the Wadi Hadramaut, an inland city of palm groves, mud-brick houses and a white palace that is now a museum, and a temperature data logger here serves a valley economy of dates, honey and trade in a hot, dry setting. Palm groves line the wadi floor, beekeepers bring honey from the side valleys, and markets sell dates, honey, vegetables and household goods to the villages around. A university college, hospitals and clinics serve the valley, and travellers visit the old buildings. Days are very hot, nights can be cool, and rare heavy rain sends floods down the wadi. The loggers hold their readings in memory on battery power, even with no network at all. We consider each request from Seiyun case by case before recommending anything.
The valley is very hot and dry by day, noticeably cooler at night, and prone to sudden flash floods after rain, so date and honey stores swing between dry heat and brief damp while clinic refrigerators work through long hot spells.
Areas
Growers pick and store dates in shaded sheds and cool rooms among the palms, where heat in the weeks after harvest is the main danger to the fruit.
Honey from the side valleys, dates, vegetables and household goods are sold in a busy central market, in shops and back rooms that heat up under the midday sun.
The old palace and other heritage buildings hold collections and archives in rooms of thick mud brick, where steady temperature and humidity protect paper, textiles and objects.
Hospitals, clinics and a college with laboratories hold vaccines, medicines and samples in refrigerators that need a dated record through power interruptions.
Industries
Date packers, honey dealers and grocers hold goods that lose quality in heat, and a record from each store shows a buyer how a lot was kept after harvest.
Hospitals and clinics serve the whole valley, and an alert on a phone reaches the duty staff at once if a vaccine or blood refrigerator warms in the night.
College and clinical laboratories keep samples and reagents to set limits, and an exported log is ready whenever a review calls for one.
Goods reach the valley over long roads, and a logger placed in a load shows how long it stood in a vehicle in the afternoon sun.

Why Prithvi
FAQ
A logger in the store records temperature and humidity through the season, and a report for the dates of a lot can be exported in PDF, Excel or CSV form for a buyer. See how a Prithvi temperature data logger works.
Send the place, the rooms and a contact through the enquiry form or WhatsApp, and we reply with what seems practical, since Yemen requests are considered case by case.
Water and silt can reach low rooms and cut the power, so the logger body is mounted above the likely water line and a battery keeps the record going through the outage.
For clinic and college laboratories in Seiyun, VEGA Calibrations, our parent company, looks after calibration; share the model and range and we outline the choices.
