About monitoring here
A logger in Sumail mostly serves food and beverage sites, as well as hospital and blood bank sites. Sumail is a valley town in the gap that cuts through the Hajar mountains, where farms and date palms line a broad wadi and shops and workshops stand along the road linking the coast with the interior, and a temperature data logger here serves a place of farm stores, roadside shops, workshops and a clinic in hot, dry air. Growers bring dates, limes and vegetables to the roadside, lorries and cars stop at cafes and shops, and a hospital and clinics serve the valley. Summer days are fierce, nights are cooler, and storms can send floods down the wadi, while the road through the gap carries traffic all day and into the night. Enquiries from Sumail are handled through the enquiry form, Call or WhatsApp.
The gap funnels hot air along the valley by day and cooler air by night, wadi floods can follow storms in the mountains, and fine dust blows along the road, so farm stores, roadside coolers and clinic refrigerators swing between baking heat, cooler nights and the odd outage. Vehicles waiting at roadside stops reach far higher temperatures than the shaded air. Drivers stop for drinks and food at all hours, so roadside coolers are opened constantly and lose cold air with every customer, and a failed unit at a quiet stop can lose a whole day's stock before anyone notices.
Areas
Growers keep dates, limes and vegetables in sheds and small cool rooms along the wadi, where heat after picking and the odd flood damp both threaten the crop.
Shops and cafes beside the road sell drinks, dairy goods and food from coolers opened constantly through the day.
Garages and workshops keep parts and tools under metal roofs that bake in the summer sun.
The valley's hospital, clinics and pharmacies keep vaccines, insulin and medicines in refrigerators that must stay in range whenever the supply wavers.
Industries
Sumail growers, shopkeepers and cafe owners hold goods that spoil in heat, and a record from each cooler shows when a unit began to drift.
The Sumail hospital and clinics hold vaccines for a valley of scattered villages, and a phone alert reaches the person responsible if a refrigerator warms.
Pharmacies in Sumail keep stock in rooms with labelled ranges, and a dated log shows how a room behaved through the hottest weeks and any flood outage.
Goods passing through Sumail by road wait in vehicles and sheds, and a logger placed in a load records how long it stood warm.

Why Prithvi
FAQ
Yes. One logger with a phone alert can watch a lone cooler as long as a router is within reach, and more points can be added to the account later. See how a Prithvi temperature data logger works.
Flood water running down the wadi can reach low rooms and cut the supply, so a body fixed higher with a battery inside keeps the record of what the room went through.
