Dhamar · Dhamar Governorate


About monitoring here
A logger in Dhamar is arranged case by case, whether for food and beverage or laboratory sites. Dhamar is a university town on the high central plateau of Yemen, south of Sana'a, and a temperature data logger here serves a farming and market city in a cool, dry climate with cold nights. Broad plains of grain, potatoes, grapes and other crops spread around it, markets sell produce and household goods to the surrounding villages, and a university, hospitals and clinics serve the governorate. Small workshops and food stores work from compact premises along the main roads. Days are bright and nights can fall close to freezing in winter, while rain comes in a short season. The loggers keep readings in memory on battery power if a network drops. We look at each request from Dhamar case by case.
The plateau is high, bright and dry, with a wide gap between a warm afternoon and a frosty dawn and a short rainy season, so farm stores swing between cold and warmth without much humidity. Stores with metal roofs warm quickly on bright winter afternoons, and the same room can fall close to freezing before dawn. Farmers and traders often hold produce for days before selling, so the long middle part of its time in storage, not the journey, decides how much is lost.
Areas
Growers keep potatoes, grapes and grain in sheds and cellars, where a frosty night and a bright afternoon both threaten the crop.
Dealers and shopkeepers sell produce, flour, oil and household goods from stock rooms in simple buildings that follow the weather outside.
A university with teaching laboratories keeps reagents and samples in refrigerators and freezers that need a dated record through power interruptions.
Hospitals, clinics and pharmacies hold vaccines and medicines in refrigerators that must hold their range through cold nights and warm afternoons.
Industries
Dhamar produce dealers and grocers hold potatoes, grapes and packaged food that suffer from frost and from warmth, and a log shows a buyer how a lot was kept.
University laboratories in Dhamar keep reagents and samples to set limits, and an exported report is ready whenever a review calls for one.
Dhamar hospitals and clinics hold vaccines and blood products for the plateau, and a phone alert reaches the person on duty if a refrigerator drifts overnight.
Pharmacies and medicine wholesalers in Dhamar keep stock to labelled ranges, and a dated log shows how a room behaved from a frosty dawn to a warm noon.

Why Prithvi
FAQ
Yes. Potatoes and fruit can be damaged by frost as easily as by heat, so a continuous log shows swings that a single spot reading would miss. See how a Prithvi temperature data logger works.
One logger with a phone alert can watch a vaccine refrigerator if a router is within reach, and further points can be added to the same account later.
