Dual Comm

Dual communication technology for uninterrupted data capture

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.

Data Logger

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.

Gateway

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.

LOGGER DEVICE
Real-Time Temperature Monitoring,
Powered by Data Loggers

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.

LTE Standalone Monitoring

A configuration in which the logger measures temperature and transmits it directly over LTE — no additional devices required.

LTE + BLE Gateway Monitoring

A configuration in which multiple BLE temperature sensors are consolidated through a single LTE gateway.

Data Logger

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.

LTE Data Logger [ LTE + BLE ]


- Transmits temperature data to the cloud in

   real time over low-power LTE.

- Data held in onboard memory during

Gateway

The gateway is the core device that transmits temperature and humidity data collected from BLE temperature data loggers to the cloud. 
m2Cloud offers two types of gateways to choose from, tailored to your on-site communication environment.

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.

- 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.
