About monitoring here
A logger in Najran mostly serves food and beverage sites, as well as hospital and blood bank sites. Najran lies in a broad fertile valley in the south of the kingdom, where mountains meet the desert, and a temperature data logger here serves an oasis city of farms, markets and a university. Date palms, pomegranates, grapes and other fruit and grain grow along the wadi, a dam holds back seasonal floods, and traders in the city markets stock food, household goods and building materials for the whole region. A university campus, hospitals and clinics bring laboratories and wards, and an industrial city on the edge of town adds plants and warehouses. Summers are hot and dry. Prithvi can supply WiFi loggers from India for a date store, a clinic or a depot, and our team gets alerts and users working by phone or video.
Summers are hot and dry, winters are mild to cool and rain, when it comes, arrives in heavy bursts, so date and fruit stores must hold a steady range through the long hot months and survive a flash flood and the dust that follows it.
Areas
Growers in the valley pick and store dates, pomegranates, grapes and grain in shaded sheds and cool rooms, where heat in the weeks after harvest is the main danger.
Traders in the markets and depots stock food, household goods and medicines, in compact shops and warehouses that fill with hot air at every delivery.
A university campus and the city's hospitals and clinics hold samples, vaccines and medicines in refrigerators and freezers that need a dated record.
Plants and warehouses in the industrial city store food, packaging and building materials in large halls that depend on cooling plants against the heat.
Industries
Date growers, fruit packers and food wholesalers hold goods that lose quality in warmth, and a record from each store shows a buyer how a lot was kept from harvest to sale.
Hospitals serve the valley and the villages in the hills, and an alert on a phone reaches the duty staff at once if a vaccine or blood refrigerator warms.
University and clinical laboratories keep samples and reagents with their own limits, and an exported log is ready for a review.
Trucks bring goods across long roads to the valley, and a logger placed in a load records how long it stood in a vehicle in the afternoon sun.

Why Prithvi
FAQ
A logger in the packing shed and the cold room records temperature and humidity through the season, and a report for the dates of a lot can be sent to the buyer. See how a Prithvi temperature data logger works.
One logger is registered to your dashboard on arrival and a short call sets its limits and the phone numbers for alerts, with a router within reach of the room.
Water and silt can reach low stores and cut the power, so mounting the logger body above the likely water line and keeping a battery in it preserves the record of what happened.
VEGA Calibrations, our parent company, handles calibration of loggers and probes; share the model and the range and we explain what can be arranged.
