Narrowband Internet of Things (NB-IoT) is a cellular communication technology built specifically for IoT devices. Unlike Wi-Fi or Bluetooth, NB-IoT operates on licensed spectrum — the same networks used by mobile carriers — which means it works in remote paddocks, underground facilities, cold rooms, and industrial sites where other wireless technologies simply can’t reach.
NB-IoT devices transmit small packets of data at regular intervals, consuming very little power in the process. A single set of batteries can last several years, making these loggers ideal for set-and-forget deployments where access is difficult or infrequent.

An NB-IoT data logger measures a physical parameter — temperature, humidity, pressure, pulse count, or others — at a set interval, then transmits that reading directly to a cloud platform over the cellular network. No gateway, no Wi-Fi router, no on-site IT infrastructure required.
Readings appear in real time on the EFENTO Cloud platform or your own system via API. Alerts can be configured to notify you by email or push notification the moment a value goes outside your defined range — whether that’s a refrigerator warming up overnight or a pipe pressure dropping unexpectedly.
Both technologies use cellular networks, but they serve different use cases.
NB-IoT is optimised for devices that send small, infrequent data packets and need to run on battery power for extended periods. If you’re monitoring temperature in a remote location, tracking water levels in a tank, or logging humidity in a storage facility, NB-IoT is almost always the better fit — longer battery life, lower cost per device, and excellent penetration through walls and into basements.
4G IoT (our GSM range) is better suited to applications requiring higher data throughput, faster update intervals, or video. If your application demands real-time streaming or large file transfers, 4G is the right choice.

Cold Chain & Food Safety Maintain compliance with temperature monitoring across refrigerated transport, cool rooms, and food processing facilities. NB-IoT loggers provide continuous records with automatic alerts, supporting HACCP and food safety audit requirements without any manual data collection.
Agriculture & Environmental Monitoring Deploy sensors across properties to monitor soil conditions, water tank levels, weather parameters, or livestock facility environments. NB-IoT’s long range and low power consumption make it practical for remote sites where running power or installing Wi-Fi is not viable.
Pharmaceutical & Life Sciences Ensure storage conditions for temperature-sensitive medications, vaccines, and biological samples meet regulatory requirements. Automated cloud logging creates the audit trail required for TGA compliance without manual log sheets.
Industrial & Utilities Monitor pipe pressure, differential pressure, and process variables across plant facilities. NB-IoT loggers can be installed in locations where running cables is impractical, with data feeding directly into your SCADA or monitoring system via API.
Building & Facilities Management Track temperature, humidity, and water leak detection across commercial buildings, data centres, and heritage-listed properties where maintaining controlled environments is critical.
NB-IoT operates on the Telstra and Optus networks in Australia. Coverage is extensive across metropolitan, regional, and many rural areas. Before deploying in a remote location, we recommend checking the carrier’s NB-IoT coverage map for your specific site. Our team can assist with this assessment.
Battery life depends on the measurement interval and transmission frequency, but most EFENTO NB-IoT loggers deliver 3–5 years of operation on a standard battery at typical logging intervals. Reducing the transmission frequency extends battery life further.
Yes. EFENTO NB-IoT loggers require a NB-IoT compatible SIM. You can use a compatible SIM from a local carrier. We have tested successfully with Telstra NB-IoT SIM cards in Australia.
Yes. The EFENTO Cloud platform provides an open API, allowing you to push data into your own SCADA, ERP, or reporting systems. MQTT and REST API protocols are supported.
Accuracy varies by model. Temperature loggers are typically accurate to ±0.3°C, humidity loggers to ±3% RH. Full specifications are listed on each individual product page.
Yes. Our NATA-accredited laboratory provides traceable calibration for temperature and humidity loggers. Calibration certificates are accepted for regulatory and audit purposes across food, pharmaceutical, and industrial applications.
