IoT Devices
Enables immediate, real-time monitoring across all logistics settings—including vehicles,
warehouses, and refrigeration units—without complex installation or extra infrastructure.
Continuously collects temperature data across the full spectrum (refrigerated, frozen, and ultra-low)
to guarantee compliant, unbroken temperature records.

The m2Cloud data logger applies two or more communication technologies at once in a single device. Even in signal-blackout environments such as tunnels, underground sections, or shadow zones where real-time transmission is impossible, temperature data stored in memory can be fully recovered after delivery via NFC tagging or BLE pairing — with nothing left out.
LTE Data Logger [ LTE + BLE ]
- Transmits temperature data to the cloud in
real time over low-power LTE.
- Data held in onboard memory during
connectivity gaps can be recovered in full
via BLE.
BLE Data Logger [ BLE + NFC ]
- Connects to a smartphone or gateway
over Bluetooth Low Energy to review
temperature data.
- Extracts large volumes of stored temperature
history with a single NFC tap from
a smartphone.
USB Data Logger [ BLE + USB ]
- Check temperatures from outside over BLE,
even while the logger is sealed inside the
transport container.
- On-site inspection without opening the
container, minimizing the risk of temperature
excursions.
A device that automatically transmits data collected from BLE data loggers to the cloud server.
WiFi Gateway [ WiFi / LAN + BLE ]
- Supports both WiFi and wired LAN, integrating flexibly with existing network environments.
- Ideal for fixed installations with established
internet access hospitals, warehouses, and
distribution centers.
LTE Gateway [ LTE-M + BLE ]
- Runs on LTE-M, so it operates the moment
power is connected — no separate internet
infrastructure required.
- Transmits real-time data from logistics sites
without internet access, and from vehicles in
transit.
Our product lineup supports the full temperature range—ultra-low (below -65°C), frozen (-20°C), and refrigerated (+2°C to +8°C)—adapting seamlessly to any bio cold chain environment.
Selected as the official monitoring device for national COVID-19 vaccine logistics, successfully maintaining strict temperature conditions for Pfizer, Moderna, Janssen, and AstraZeneca over multiple years.
Two configurations are available depending on your delivery environment and monitoring setup. Watch the videos below to see how each one collects temperature data, transmits it to the cloud, and puts it under real-time monitoring.
A configuration in which the logger measures temperature and transmits it directly over LTE — no additional devices required.
A configuration in which multiple BLE temperature sensors are consolidated through a single LTE gateway.

Even in signal-blackout environments such as tunnels, underground sections, or shadow zones where real-time transmission is impossible, temperature data stored in memory can be fully recovered after delivery via NFC tagging or BLE pairing — with nothing left out.
The data logger is the core IoT device that measures temperature and humidity data.
m2Cloud offers three types of data loggers to choose from, tailored to your operating environment.

Our product portfolio supports the entire spectrum—Ultra-Low (≤-65°C), Frozen (-20°C), and Refrigerated (+2°C to +8°C)—adapting to any bio cold chain environment.
Selected as South Korea's official COVID-19 vaccine monitoring system, flawlessly fulfilling strict temperature requirements for Pfizer, Moderna, Janssen, and AstraZeneca for years.
Operates in two configurations depending on your delivery environment and monitoring needs. Watch the video below to see how each setup collects, transmits, and monitors temperature data in the cloud.
A configuration in which the logger measures temperature and transmits it directly over LTE — no additional devices required.
A configuration in which multiple BLE temperature sensors are consolidated through a single LTE gateway.
