About monitoring here
A logger in Lahij is arranged case by case, whether for food and beverage or hospital and blood bank sites. Lahij, also known as Al Hawta, is a market town on a fertile delta plain in the south of Yemen, a short way north of Aden, and a temperature data logger here serves a farming district where heat, flood and dust meet. Floodwater from the highlands has long watered fields of cotton, vegetables, fruit and fodder, growers bring their crops to the town markets, and traders carry goods on towards Aden and the mountains. Clinics, small hospitals and pharmacies serve the district, and shops sell food and household goods. The climate is hot, with humidity that rises towards the coast. The loggers hold their readings in memory on battery power whenever the network drops. We consider each request from Lahij case by case.
The plain is hot for most of the year, humid in the weeks when the sea air reaches inland, and dusty in the dry months, while rain is uneven and sometimes arrives as flood, so produce stores and clinic refrigerators work through long hot spells and interrupted power. Wholesalers load in the cool early hours to avoid the midday sun, but a cargo packed at dawn can still sit in a hot vehicle for much of the day before it is unloaded.
Areas
Growers of vegetables, fruit and fodder crops keep produce in sheds and small cool rooms, where heat after picking and flood damp both threaten quality.
Dealers sort and load produce in open yards and sheds, and the hours of waiting before a lorry leaves decide how much of a crop spoils.
Shops sell milk, yoghurt, drinks and packaged food from small rooms with simple coolers, opened constantly through the day.
Clinics and pharmacies hold vaccines and medicines in refrigerators that must hold a range through hot afternoons and power cuts.
Industries
Lahij produce dealers, dairy sellers and grocers hold goods that spoil quickly in heat, and a record from each cold room shows when a chiller or an ice box began to fail.
Lahij clinics and small hospitals hold vaccines and blood products for the district, and an alert on a phone reaches the right person if a refrigerator warms.
Pharmacies in Lahij keep stock in rooms with stated ranges, and a dated log shows how a room behaved through the hottest weeks and any outage.
Produce loaded in Lahij for Aden and the mountains stands in vehicles in the sun, and a logger placed in a load records what the cargo met on the way.

Why Prithvi
FAQ
Yes. One logger with an alert to a phone can watch a single refrigerator in a clinic or shop, provided a router is within reach, and further points can be added to the same account later. See how a Prithvi temperature data logger works.
Tell us the place, what you store and a contact through the enquiry form or WhatsApp. Yemen requests are weighed case by case, and we reply with what seems workable.
A flood can carry water and silt into low rooms and cut the supply, so a body fixed higher up and fitted with a battery keeps the record of what the room went through.
VEGA Calibrations, our parent company, looks after calibration of loggers and probes for Lahij sites; share the model and the range and we explain the options.
