WiFi and GSM temperature & humidity monitoring for Rohtak's pharma, cold chain and industrial sites.
Rohtak · Haryana


About monitoring here
Rohtak lies west of Delhi on the highway towards Hisar, and it works as the district town for a wide farming region while also holding a medical institute, a university and a ring of small factories. Its storage is a blend of the clinical and the commercial: wards, pharmacies and laboratories around the large government medical institute, medicine stockists who supply smaller towns, grain and vegetable markets, and workshops and engineering units in the industrial estates on the Delhi side. A temperature data logger in Rohtak therefore guards vaccines and reagents in one lane and sacks of produce or packed goods in the next. Many of these stores are staffed by a small team on fixed shifts, and a reading that arrives on a phone after hours is more useful than one found at the next morning's round. Prithvi supplies WiFi and GSM loggers for rooms and vehicles alike.
The plains here are very hot and dry through the long summer, the monsoon turns the air humid for a spell, and winter nights are cold with fog that delays supply vans on the highway.
Areas
The large government medical institute and the hospitals, pharmacies and diagnostic laboratories around it keep vaccines, blood components and reagents in many refrigerators that must hold their limits through power cuts.
Teaching and research laboratories on the campus store samples, chemicals and cultures in freezers and cabinets, some of them in buildings that stand empty at night and on holidays.
Engineering workshops, component makers and packing units on the Delhi side of the city store paints, lubricants and packed goods in sheds of mixed age and size.
Traders hold sacks of grain and baskets of produce in godowns and market yards, where damp air and midday sun decide how long the stock stays sound.
Industries
Hospitals around the medical institute rely on blood storage units and vaccine refrigerators on every floor, and a phone alert after a power cut lets the duty technician move stock to a cooler unit in time.
University and diagnostic laboratories hold samples and reagents in freezers and incubators, and a logged record shows a research sponsor or an examiner that the conditions held through weekends and holidays.
Medicine stockists in the city supply chemists across a wide rural area, and a record from each store shows that tablets and injectables stayed within the printed limits before they left on a van.
Packed-food makers and grain traders hold stock in warm sheds, and a humidity and temperature trend shows when a damp spell has begun to threaten sacks and cartons.

Why Prithvi
FAQ
Each ward, pharmacy or laboratory can be set up as a named location with its own alert contacts, so the duty technician sees a drifting unit on the phone and the pharmacist sees the full list on a desktop.
Loggers keep recording on their batteries and send the stored readings when the network returns, and an alert for the lost mains supply can go to the person responsible for the room.
Send the market, the lane or the plot, the rooms to look at and a person who will meet us. We agree the day around trading hours or shift times, and we choose positions for the loggers on site before any are fixed.
A multi-channel logger can watch a main freezer and its standby unit through two probes, and one report then shows whether both held their limits when the first one failed. See how a Prithvi temperature data logger works.
