Al Majmaah · Riyadh Region


About monitoring here
A logger in Al Majmaah mostly serves food and beverage sites, as well as logistics and warehousing sites. Al Majmaah is the main town of the Sudair region, on the plain north of Riyadh on the road toward Qassim, and a temperature data logger here serves an oasis town of farms, a university and growing industry. Wells irrigate date palms, wheat, fodder and vegetables, dairy and poultry farms supply the markets of the capital, and a public university has its campus in the town with laboratories and clinics. Hospitals and health centres serve the surrounding villages, and a newer industrial city in the Sudair region adds plants and warehouses. Summers are extremely hot and dusty. Prithvi supplies WiFi loggers from India with alerts to phones and email and sets them up with your team remotely, so a manager can follow a room without being on site.
The plain is scorching for much of the year, dust storms are common in spring and the few winter rains can arrive suddenly, so farm cold rooms and date stores work at their limits and a failed unit can lose a harvest day.
Areas
Growers pick, sort and pack dates in shaded sheds and cool rooms, where steady temperature and low humidity protect the fruit through months of storage.
Farms around the town chill milk, hold chilled poultry and pack vegetables in cold rooms, with trucks carrying the output to Riyadh through the heat of the day.
A public university and the town's hospitals hold samples, vaccines and medicines in refrigerators and freezers on a campus and in wards spread over a wide area.
A newer industrial area in the Sudair region adds plants and warehouses whose stores hold food, packaging and building materials in large halls cooled against the heat.
Industries
Date packers, dairy farms and poultry businesses hold product that loses quality in heat, and a record from each room shows a buyer how a lot was kept from harvest to loading.
Trucks of produce and chilled goods travel the highway toward Riyadh and Qassim, and a logger in a load shows how long goods stood in a vehicle on the road.
University and testing laboratories keep samples and reagents in freezers and fridges with their own limits, and an exported log supports a review.
Hospitals and health centres hold vaccines and medicines for a scattered population, and an alert to the duty staff reaches the right person at once if a refrigerator warms.

Why Prithvi
FAQ
A logger in the packing store and the cold room records temperature and humidity through the season, and the report shows a buyer how a lot was kept from picking to loading. See how a Prithvi temperature data logger works.
Once the loggers arrive from India they are registered to your dashboard, and a short call or video session sets the rooms, the limits and the alert contacts, with a router in range of each room for the WiFi logger.
Fine dust settles on vents and probe tips, so we place the logger body away from the dustiest doors, keep probes sealed and suggest wiping them at routine cleaning.
Calibration of loggers and probes is handled by our parent company, VEGA Calibrations. Share the model and the range you use and we confirm the options.
