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


About monitoring here
Hisar stands in the dry western part of Haryana and combines heavy metal industry with a large farm-science base. Steel and galvanised-iron works fill its industrial areas, while an agricultural university and national research centres for buffaloes and horses give the town laboratories, seed stores, animal-health stores and veterinary cold rooms that few cities of its size possess. Cotton, oilseed and grain from the surrounding farms pass through its markets and mills. A temperature data logger in Hisar is therefore as likely to guard a vaccine refrigerator in a research farm as the coolers of a food business or a chemical store at a steel unit. The summer here is fierce, and a store that is comfortable in March can be dangerous by May. Prithvi supplies WiFi loggers for rooms with a network and GSM loggers for farm stores and vehicles, with alerts to phones and email.
Summers are fierce and dry with hot winds, the monsoon is short and winter brings cold nights and fog, so a shed or a room can pass from one extreme to the other within a single year.
Areas
Metal processing units in the industrial areas keep coatings, acids, lubricants and finished coils in sheds under tin roofs that radiate heat through the afternoon.
The farm university and the national research centres hold seed, serum, semen and vaccines in cold rooms and freezers that must keep to written protocols for years at a stretch.
Mills and traders hold cotton bales, oil and sacked grain in godowns where heat and damp air can spoil stock between one sale and the next.
Hospitals, nursing homes and laboratories keep vaccines, blood components and medicines in refrigerators that serve patients from many surrounding districts.
Industries
Research stations and university laboratories keep seed, serum and biological samples in cold rooms and freezers, and a continuous log gives a sponsor the evidence that conditions held through the hottest months.
Steel and galvanising units hold acids, zinc and coatings with printed storage limits, and an alert on a heated store gives the supervisor time to move drums before the label is breached.
Oil mills, dairies and grain traders hold stock that suffers in heat and damp, and a record from each godown helps owners decide when to ventilate, move or sell.
Hospitals and blood storage units in the city serve a wide rural area, and alerts on a phone mean a failed refrigerator is noticed at night and not at the morning round.
Recommended products
A starting point for the sites above. Our team will help you choose.

2 × temperature, or 2 × temperature + humidity (Pro)
Two-channel WiFi logger for temperature, or temperature and humidity, at two points.
Rajmudra in Hisar: Two channels watch a research cold room at its top and bottom, giving a paired record for a sponsor who wants evidence from both positions.

10 × temperature, or 10 × temperature + humidity (Pro)
Ten-channel WiFi logger for warehouses and multi-zone facilities.
Veer in Hisar: Ten channels spread through a long oilseed or cotton godown at different heights show where the stock sits in the heat and where it stays cooler.

Temperature + humidity
SIM-based GSM logger for sites and vehicles without Wi-Fi.
Vayu in Hisar: A SIM-based GSM logger reports from a farm store or a vehicle far from any building Wi-Fi, which suits vaccines and samples that travel out to the district.
These services are delivered by our parent lab, VEGA Calibrations.Ask us to plan them for your Hisar site alongside your loggers.
Process
Tell us what you store, where, and how many points need watching.
We look at the layout and conditions, by call or on a site visit, and recommend the right loggers.
Loggers are supplied and installed, then connected to your dashboard and alert recipients.
We stay available for alert rules, user access and calibration planning as your sites change.
Why Prithvi
FAQ
Loggers are rated for a wide range, and we place them out of direct sun and away from metal roofs and hot walls so that the reading reflects the stored goods and not the shed. We also suggest a high-temperature alert that fires early, while there is still time to act. See how a Prithvi temperature data logger works.
Limits, alert contacts and report intervals are set room by room to follow the written protocol, and a report for any period can be exported for a supervisor or a sponsor.
Where a store has a router we use a WiFi logger, and where it has none a SIM-based Vayu logger reports over the mobile network, so a depot in an outlying village can sit on the same dashboard as a town laboratory.
VEGA Calibrations, our parent company, delivers temperature mapping, which shows the warm and cold positions in a large godown so that permanent loggers can be placed where they matter.
