Wireless Temperature and Humidity Monitoring for Cold Rooms, Freezers, Labs and Vaults
Cold Storage Temperature Monitoring Without Opening the Door
Continuous temperature and humidity logging for cold rooms, freezers, pharmacies, laboratories, archives and vaults. Probes rated to -40 °C, the transmitter outside the chamber, an alarm the minute a limit is crossed, and a record you can hand to an auditor.
Cold Chain Losses Usually Come Down To One of These Four Things:
Manual Rounds
A clipboard check twice a day misses the twelve hours in between. A compressor fault at 22:00 is found at 06:00, after the stock is gone. Wireless monitoring logs every few minutes and alarms at once.
Sensors That Freeze
Standard indoor sensors are not built for -25 °C. VemSpace cold storage points use probes rated down to -40 °C, with the transmitter and battery mounted outside the chamber where they last.
Logs Nobody Can Defend
Auditors and insurers ask for continuous records with calibration history. Every monitoring point comes with a traceable factory calibration certificate and a planned recalibration cycle.
One More Silo
Temperature data in its own app is rarely looked at. In VemSpace it sits next to occupancy, air quality and energy data for the whole site, with one alarm setup and one report.
VemSpace
VemSpace is the IoT module of the Vemco platform, developed in-house, and it turns cold storage temperature into a log you can trust, alarms you can act on and reports you can hand over.
Wireless LoRaWAN sensors report to the cloud through indoor gateways with 4G fallback. LoRaWAN reaches through insulated walls and cold room doors where Wi-Fi struggles, so there is no cabling project and no dependency on the customer network. Dashboards, alerts, scheduled reports and API access are included for every monitoring point.
Temperature Monitoring System: What One Platform Covers
Cold Rooms & Freezers
Pharmacies & Laboratories
Archives, Seed Banks & Vaults
Warehouses & Loading Bays
Server & Plant Rooms
Alarms & Escalation
Reports & Audit Trail
Walk-in cold rooms and freezers in supermarkets, kitchens, warehouses and food production. A probe inside, the transmitter outside, readings every few minutes and high and low limits per room. A door left open shows up as the temperature curve it causes.
Vaccine fridges, sample freezers and reagent stores need a documented range, often 2 to 8 °C, and proof that it was never left. Continuous logging replaces the paper chart, and an alarm reaches the person on duty before a delivery is lost.
Long-term storage of documents, seeds, film and biological material depends on temperature and relative humidity staying stable for years. Separate temperature and humidity points with probes rated to -40 °C and the transmitter outside the vault give a continuous record without opening the door.
Temperature-controlled warehouses and loading bays are where the cold chain most often breaks. Monitor storage zones and docks, log the hand-over, and add carbon monoxide monitoring where forklifts and trucks operate.
Here heat is the risk, not cold. The same monitoring points watch temperature and humidity in server rooms, switch rooms and plant rooms and alert before equipment shuts down or condensation forms.
Set a high and a low limit and a delay per monitoring point, so a door opening does not trigger a call-out but a failing compressor does. Alarms go out by email or through the API to an escalation list, and every alarm and acknowledgement is stored with the reading that caused it.
Daily, weekly or monthly reports per site or per room, exported or pulled through the API into your quality system. The full history is kept, so a question from an auditor or an insurer twelve months later is answered in minutes.
Documentation an Auditor, an Insurer or a Tender Will Accept
Cold storage temperature monitoring is asked for by food safety schemes such as HACCP, by pharmaceutical distribution rules, by insurers after a loss and by tenders for laboratories, archives and gene banks. What they have in common is a demand for continuous records over time, not a spot check on the day of the inspection.
Every monitoring point is delivered with a traceable factory calibration certificate from the manufacturer, along with the radio type approvals and conformity documents required in your market. Annual recalibration and performance verification keep the data defensible year after year, and all readings can be exported or pulled through the API into your quality system.
Buy or Rent: Choose the Model That Fits Your Budget
Outright Purchase
Buy the sensors and gateways and license the VemSpace platform per monitoring point. The right choice when the project sits in a capital budget and you want to own the hardware.
All-Inclusive Rental
One monthly price per active monitoring point with hardware, platform and service included. No upfront investment, and temperature monitoring becomes an operating cost.
Start Small, Scale Up
Begin with one cold room or one site and add monitoring points as the need grows. Because the sensors are wireless, extending the installation takes hours, not weeks.
Service Built In
Annual recalibration, performance verification and planned replacement of batteries and probes keep the data valid for reporting for the whole lifetime of the installation.
Temperature Monitoring for Any Site
Retail
Back-of-store cold rooms and chilled cabinets in every branch, monitored centrally with one alarm setup across the whole chain.
Malls
Food courts, tenant kitchens and central cold stores documented for tenants, authorities and insurers, next to footfall and air quality.
Supermarkets
Cold rooms, freezers and chilled aisles logged continuously, with alarms before goods are lost and a record ready when the inspector asks.
Leisure
Stadium and venue kitchens, bars and event catering where stock moves fast and a failed chiller on match day is expensive.
Education & Public Institutions
Canteens, laboratories and archives with a documented temperature history the facility team can show without a paper chart.
Airports
Catering, duty-free cold stores and pharmacy stock across a terminal, on the same platform as passenger flow.
Public Transportation
Depots, station kitchens and technical rooms where temperature swings and forklift traffic meet, monitored from one place.
A Solution to Every Problem
Luksusbaby A/S
Problem
Luksusbaby wanted to view real-time, accurate KPIs regarding their physical stores, such as hit and conversion rates, for improved decision-making.
Solution
Our solution helped Luksusbaby take action based on facts rather than intuition while discovering the age of their incoming visitors for accurate conversion rate data.
Daells Bolighus
Problem
Daells Bolighus struggled to keep up with the changing market and had been in an economic deficit for 16 years. The main problems were old-fashioned marketing strategy and a lack of insight into customer data.
Solution
Vemco Group installed people counters in both Daells Bolighus stores and integrated sales and visitor data from the physical stores with online data from their website, allowing them to view and compare data across locations.
Magasin
Problem
Magasin had an outdated, unreliable people counting solution and wanted a hosted solution, exporting data into a central BI system to give them insight into customer behavior in all their department stores.
Solution
We delivered an accurate, up-to-date people counting solution to Magasin, which allowed them to reduce operational costs by outsourcing their customer data to us.
Odense Municipality
Problem
Odense Municipality wanted to access insight into how the citizens and visitors of Odense use the city and act on these insights based on factual decision-making rather than intuition.
Solution
To measure how the citizens and visitors of Odense use the shopping street, we cover all relevant entrances and exits with weather-resistant sensors that cover heights up to 20 meters.
Frequently Asked Questions
What is cold storage temperature monitoring?
Cold storage temperature monitoring is the continuous, automatic measurement and logging of temperature, and usually humidity, in cold rooms, freezers, refrigerators, archives and vaults. Wireless sensors send readings every few minutes to a platform that stores the history, raises alarms when a limit is crossed and produces the reports auditors ask for.
How does a wireless temperature monitoring system work?
A probe sits inside the cold space and is connected to a transmitter mounted outside the chamber. The transmitter sends readings over LoRaWAN to an indoor gateway, which connects to the VemSpace cloud with 4G as fallback. No cabling and no access to your IT network are needed.
How cold can the sensors go?
The probes used for cold storage points are rated down to -40 °C. Because the transmitter and battery sit outside the chamber, battery life and radio range are not affected by the cold.
Can it monitor humidity as well as temperature?
Yes. Cold storage points are available as combined temperature and humidity points, which matters for archives, seed banks and vaults where relative humidity has to stay stable for years.
How are alarms handled?
You set a high and a low limit and a delay per monitoring point. When a limit is exceeded for longer than the delay, VemSpace notifies the people on the escalation list by email or through the API, and logs the alarm and the acknowledgement together with the readings.
Is the data good enough for an audit?
Each sensor is supplied with a traceable factory calibration certificate from the manufacturer, and we recommend annual recalibration and performance verification. The full reading history is stored and can be exported or pulled through the API.
Can we buy the system or rent it?
Both. You can buy the sensors and gateways and license VemSpace per monitoring point, or take an all-inclusive monthly rental per active monitoring point with hardware, platform and service included.
Can temperature data be combined with other building data?
Yes. VemSpace is part of the same platform as VemCount, so cold storage temperature can be shown next to indoor air quality, occupancy and footfall for the same site, with one login and one report.
