Reliable temperature monitoring over the mobile network, even at hard-to-reach measuring points.
This wireless NB-IoT temperature data logger measures from -55°C to +125°C and operates via a SIM card. Includes free app, replaceable battery and an external sensor with a 3-meter cable.
Please note: purchase of a SIM card and cloud subscription is required. See the accessories at the bottom of this page.
Description
The logger is equipped with an external, waterproof probe that makes it possible to measure temperature at points where the sensor cannot be placed directly. The probe is available in two variants: standard, or designed for food contact, in the form of a sharpened spike.
Efento NB-IoT sensors transmit data over the mobile network (Narrowband IoT) and require no additional devices such as a router or gateway. The sensors are also equipped with a Bluetooth Low Energy interface, allowing quick and easy configuration with a smartphone. Efento NB-IoT sensors can be integrated with any cloud platform.
Features
- Temperature: -55°C to +125°C
